While contemporary accounts understand esteem and self-esteem as essentially competitive phenomena, early modern natural law theorists developed a conception of justified esteem and self-esteem based on naturally good character traits. This article explores how such a normative conception of esteem and self-esteem is developed in the work of Christian Wolff. Two features make Wolff’s approach distinctive: He uses the analysis of common notions that are expressed in everyday language to provide a foundation for the aspects of natural law (...) on which his conception of natural duties of esteem depends. He develops a non-competitive conception of esteem and self-esteem into a cooperative conception, according to which enhancing the esteem in which others are held is seen as a tool for promoting self-perfection. Wolff’s ideas offer a solution to the well-known problems connected with competitive life-styles, and at the same time assign a central role in moral motivation to the desire of being esteemed and of having high self-esteem. Moreover, due to his emphasis on presenting a philosophical analysis based on common notions, he offers a solution that is meant to be persuasive from the perspective of everyday morality. (shrink)

In this paper I explore the ways in which Alexander of Aphrodisias employs and develops so-called ‘common notions’ as reliable starting points of deductive arguments. He combines contemporary developments in the Stoic and Epicurean use of common notions with Aristotelian dialectic, and axioms. This more comprehensive concept of common notions can be extracted from Alexander’s commentary on Metaphysics A 1–2. Alexander puts Aristotle’s claim that ‘all human beings by nature desire to know’ in a (...) larger deductive framework, and adds weight to Aristotle’s use of the common understanding of the notion of ‘wisdom’. Finally I will indicate how these upgraded common notions are meant to play an important role in the general framework of metaphysics as a science. (shrink)

In his defense of innateness in New Essays on Human Understanding (1704), Leibniz attributes innateness to concepts and principles which do not originate from the senses rather than to the ideas that we are born with. He argues that the innate concepts and principles can be known in two ways: through reason or natural light (necessary truths), and through instincts (other innate truths and principles). In this paper I will show how theoretical and moral reasoning differ from each other in (...) Leibniz, and compare moral reasoning and instincts as sources of knowledge in his practical philosophy. As the practical instincts are closely related to pleasure and passions, which are by nature cognitive, my emphasis will be on the affective character of instinctive moral action and especially deliberation which leads to moral action. I will argue that inclinations arising from moral instinct, which lead us to pleasure while avoiding sorrow, can direct our moral action and sometimes anticipate reasoning when conclusions are not readily available. Acting by will, which is related to moral reasoning, and acting by instincts can lead us to the same moral knowledge independently, but they can also complement each other. To illustrate the two alternative ways to reach moral knowledge, I will discuss the case of happiness, which is the goal of all human moral action for Leibniz. (shrink)

Discussions of the relation between confessionalization and early modern natural philosophy have tended to focus on the influence of certain theological doctrines characteristic of the different Christian denominations on specific analyses of the material world. By contrast, I would like to argue that an obstacle to formulating all-too general confessionalization claims derives from ecumenical uses of early modern natural philosophy that serve to provide rational grounds for commonly acceptable theological views. One such ecumenical approach can be found in the work (...) of Kenelm Digby. I develop such a line of interpretation by comparing Digby’s argumentative strategy with the argumentative strategies of one of his readers, Gottfried Wilhelm Leibniz, who in his early writings developed a sophisticated version of mechanical philosophy. Leibniz refers to Digby’s analysis of the powers of organisms, and, like Digby, he uses the limits of these powers as arguments for the existence of immaterial, and hence immortal human souls. The convergence between Digby and the early Leibniz on this central theological point can be seen as an outcome of the analysis of our common notions concerning the nature of matter and of the analysis of our common notions concerning the mental capacities of humans.

The “common notions” prefacing the Elements of Euclid are a very peculiar set of axioms, and their authenticity, as well as their actual role in the demonstrations, have been object of debate. In the first part of this essay, I offer a survey of the evidence for the authenticity of the common notions, and conclude that only three of them are likely to have been in place at the times of Euclid, whereas others were added in (...) Late Antiquity. In the second part of the essay, I consider the meaning and uses of the common notions in Greek mathematics, and argue that they were originally conceived in order to axiomatize a theory of equivalence in geometry. I also claim that two interpolated common notions responded to different epistemic needs and regulated diagrammatic inferences. (shrink)

This paper argues for two claims. (1) In his biological views, Kenelm Digby tries to reconcile aspects of an Aristotelian theory of composite substance with early modern corpuscularianism. (2) From a methodological point of view, he uses the Stoic-Epicurean epistemology of common notions in order to show the adequacy of his conciliatory approach. The first claim is substantiated by an analysis of Digby’s views on the role of mixture and homogeneity in the process of animal generation. The second (...) claim is substantiated by an analysis of Digby’s views on the role of the concept of quantity in the evaluation of scientific hypotheses. Both arguments make use of the context of Digby’s philosophy: the first argument draws on his background in the work of early modern corpuscularian Aristotelians such as Daniel Sennert; the second argument draws on his background in the epistemology of Pierre Gassendi.

This chapter takes a closer look at the doctrine of common notions and universal consent developed by Nathaniel Culverwell (1619–51) in his Elegant and Learned Discourse of the Light of Nature, a work based on lectures delivered at Cambridge in 1645–46, but only published posthumously in 1652. I study Culverwell’s doctrine of common notions and universal consent from the perspective of his critical discussion of two contemporary works, namely Descartes’s Discours de la méthode (1637) and Robert (...) Greville’s The Nature of Truth (1640). I argue that, contrary to Wallis who was indeed an Aristotelian who rejected innate ideas entirely, Culverwell adopted a characteristically stoic position, according to which common notions do not directly derive from sense experience, but are innate dispositions common to all which become present to the mind only under the impact of the senses.

In this paper I offer three main challenges to James (2011). All three turn on the nature of philosophy and secure knowledge in Spinoza. First, I criticize James's account of the epistemic role that experience plays in securing adequate ideas for Spinoza. In doing so I criticize her treatment of what is known as the ‘conatus doctrine’ in Spinoza in order to challenge her picture of the relationship between true religion and philosophy. Second, this leads me into a criticism of (...) her account of the nature of philosophy in Spinoza. I argue it is less piecemeal and less akin to what we would recognize as ‘science’ than she suggests. Third, I argue against James's core commitment that Spinoza's three kinds of knowledge differ in degree; I claim they differ in kind. My argument will offer a new interpretation of Spinoza's conception of ‘common notions’. Moreover, I argue that Spinozistic adequate knowledge involves something akin to angelic disembodiment.

In this chapter, I explore this complex and somewhat neglected tradition of the early modern common notion. I focus on three thinkers, two of them innatist in some sense, one of them not; all (mostly) products of the English context; all arguably part of the background for Locke’s critique of common notions and innate ideas in the first book of the Essay; and all related to each other in various and complicated ways. They are: Edward Herbert of (...) Cherbury (1582–1648), Kenelm Digby (1603–1665), and Nathaniel Culverwell (1619–1651). I show how they deployed three different theories of common notions that we can describe, respectively, as gnoseological, rhetorical, and allegorical. (shrink)

The formal theory of the Model of Hierarchical Complexity is presented. Complexity theories generally exclude the concept of hierarchical complexity; Developmental Psychology has included it for over 20 years. It also applies to social systems and non-human systems. Formal axioms for the Model are outlined. The model assigns an order of hierarchical complexity to every task, using natural numbers, establishing a quantal notion of stage and stages of performance. This formalizes properties of stage theories in psychology. The formal theory of (...) the model enables extending the concept of hierarchical complexity to any field where tasks and their performances exist. (shrink)

It is shown that, given any finite set of pairs of random events in a Boolean algebra which are correlated with respect to a fixed probability measure on the algebra, the algebra can be extended in such a way that the extension contains events that can be regarded as common causes of the correlations in the sense of Reichenbach's definition of common cause. It is shown, further, that, given any quantum probability space and any set of commuting events (...) in it which are correlated with respect to a fixed quantum state, the quantum probability space can be extended in such a way that the extension contains common causes of all the selected correlations, where common cause is again taken in the sense of Reichenbach's definition. It is argued that these results very strongly restrict the possible ways of disproving Reichenbach's Common Cause Principle. (shrink)

The paper aims to discuss the notion of ‘common sense’ in Thomas Reid’s philosophy. It presents two hypotheses. The first hypothesis states that the common sense that Reid uses in philosophical matters is nothing but the set of original principles of the mind that determine human beings in regard to their notions, beliefs and inclinations, as well as the judgments and beliefs that are due to these principles. The second hypothesis states that Reid understands a kind of (...) ‘developed common sense’, a common sense that develops throughout human life by the proper cultivation of the powers of the mind.

The paper addresses a mainstream contemporary view of the notion of common sense in Thomas Reid’s philosophy, as proposed by Nicholas Wolterstorff who claims that Reid was not clear about the concept of common sense, or about the principles of common sense. In contrast, this paper presents Reid’s conception as a clear and traditional Aristotelian notion of common sense and its principles as presuppositions of particular sense judgments, usually taken for granted. The alleged confusion about principles (...) is resolved by a distinction between principles of common sense and first principles as such. (shrink)

In recent years, the international commons movement has increasingly joined forces with the global movement of municipalities, putting common ideas on the political agenda in many western countries. Commons have been widely discussed in literature. Broadly understood, commons refers to the practices for collective development, ownership, management, and fair access to resources and artifacts (social, cultural, economic, political, environmental, and technological). However, the concept remains vague, complex, and unclear, especially when it comes to different contexts in which new definitions (...) are needed to better understand the societal and cultural dimensions of urban commons. Decolonizing the notion of urban commons brings into visibility the unseen cultures, infrastructural systems, and communities showing where de-growth and separation can take place. Therefore, this analysis can provide new insights, opportunities, and the need for new theoretical, methodological, and shared approaches. There is a gap in transnational research and cultural understanding within the field of urban commons. This research opens new lines of inquiry relating to the definitions of commons in non-European countries. This may include longitudinal research on the decolonization and potential fragmenting of the commons and in particular 'commoning' mindset, more detailed empirical evidence of the cultural and communal concepts, and how these cultural diversities and new interpretations can be implemented in collaborative governance in a wider variety of non-western contexts. By challenging existing frameworks, this study facilitates the emergence of differentiated, dynamic, and non-linear forms of social and political subjectivity within various sociospatial domains.

A common coding account of bidirectional evaluation–behaviour interactions proposes that evaluative attributes of stimuli and responses are coded in a common representational format. This assumption was tested in two experiments that required evaluations of positive and negative stimuli during the generation of a positively or negatively charged motor response. The results of both experiments revealed a reduced evaluative sensitivity (d′) towards response-compatible stimulus valences. This action–valence blindness supports the notion of a common valence coding in action and (...) evaluation. (shrink)

I explore the possible meanings that the notion of the common morality can have in a contemporary communitarian approach to ethics and public policy. The common morality can be defined as the conditions for shared pursuit of the good or as the values, deliberations, traditions, and common construction of the narrative of a people. The former sense sees the common morality as the universal and invariant structures of morality while the second sense is much more contingent (...) in nature. Nevertheless, the communitarian sees both aspects as integral in devising solutions to public policy problems. I outline how both meanings follow from communitarian philosophical anthropology and illustrate how they work together when addressing a question such as that of providing universal health insurance in the United States. The common morality forms the basis of building an implicit consensus that is available to and reaffirmed by the shared reflections of the citizenry. (shrink)

This essay analyzes Roman Catholic social teaching on the right to health care and the legitimacy of healthcare rationing. It considers that discussion at two levels: (1) the specific warrants that undergird key terms; and (2) the accessibility and applicability of those warrants to policy choices in a secular society. The essay concludes with a number of broader reflections meant to reserve an appropriate place for religious voices in the process of policy-making, as distinguished from its justification.

Truth is a fundamental philosophical concept that, despite its common and everyday use, has resisted common-sense formulations. At this point, one may legitimately wonder if there even is a common-sense notion of truth or what it could look like. In response, I propose here a common-sense account of truth based on four “truisms” that set a baseline for how to go about building an account of truth. Drawing on both ordinary language philosophy and contemporary pragmatic approaches (...) to truth, I defend a pragmatic, common-sense theory of truth. The result is a theory that focuses the use and function of truth while also emphasizing its “subject-independence.”. (shrink)

In this article, I take a fresh look at the logic of common and natural notions contained in the Two Treatises published in 1644 by Kenelm Digby (1603–1665). Digby's doctrine of common notions was an attempt to retrofit Aristotelianism in order to bring it out of the shadows of scholasticism and into the age of the new experimental and collaborative natural philosophy. To achieve that, he argued that natural philosophy began in the world of experience expressed (...) in common language and was structured according to the basic principles he calls common notions. Taking my point of departure in his correspondence with Hobbes and Mersenne, I explore the Epicurean roots of this theory. (shrink)

Opracowanie dotyczy relacji konstytucyjnego pojęcia „dobro wspólne” z art. 1 Konstytucji RP, do pozaprawnych pojęć dobra wspólnego. Bezpośredni asumpt do jego przygotowania dało zdanie odrębne sędziego Trybunału Konstytucyjnego Zbigniewa Cieślaka do wyroku TK z dnia 20 kwietnia 2011 r. w sprawie Kp 7/09, dotyczącej zmian w prawie budowlanym. Jest to w ogóle najobszerniejsza wypowiedź w całym dotychczasowym orzecznictwie TK poświęcona wprost problematyce dobra wspólnego. Sędzia Z. Cieślak wyraźnie odróżnił prawne pojęcie dobra wspólnego – jego zdaniem właściwe dla interpretacji klauzuli dobra (...) wspólnego z art. 1 Konstytucji RP z 1997 r. – od pojęć pozaprawnych, uznając te ostatnie za źródło nieporozumień w prawniczych dyskusjach na temat rozumienia wyrażenia „dobro wspólne” w prawie i jako kategorii konstytucyjnej. Argumentować będę, że zrekonstruowane przez Z. Cieślaka prawne pojęcie dobra wspólnego nie nadaje się do interpretacji klauzuli dobra wspólnego z art. 1 konstytucji z 1997 r., i że pojęcia pozaprawne powinny być postrzegane nie jako źródło nieporozumień, ale jako nieodzowna pomoc w ustalaniu treści konstytucyjnego pojęcia dobra wspólnego. Problematyka ta prowadzi do podjęcia pewnego – kluczowego dla stosowania art. 1 – zagadnienia relacji między dobrem wspólnym a prawami człowieka (wolnościami i prawami człowieka), zagadnienia, które ostro zarysowało się w orzecznictwie trybunalskim po raz pierwszy właśnie w tym zdaniu odrębnym. Chodzi mianowicie o związki zachodzące między dwoma zasadniczymi tradycjami pojmowania dobra wspólnego i odpowiadającymi tym tradycjom dwoma typami pojęć dobra wspólnego – tradycji klasycznej, znajdującej swój wyraz w Konstytucji 3 maja z 1791 r., i tradycji, w której dobro wspólne pojmowane jest przede wszystkim jako dobro państwa i która znalazła wyraz w konstytucji kwietniowej z 1935 r. Dla pierwszej tradycji charakterystyczne jest uznanie praw człowieka za zasadniczy element dobra wspólnego – i tę tezę Z. Cieślak akceptuje. Analiza jego propozycji pokazuje jednak, że należy ona do tradycji konstytucji kwietniowej, a przyjęcie pojęcia dobra wspólnego należącego do tej tradycji prowadziłoby do niespójności z niektórymi fundamentalnymi rozstrzygnięciami ustrojodawcy, dotyczącymi tak interpretacji art. 1 konstytucji i przyjętej w nim koncepcji dobra wspólnego, jak i konstytucyjnej koncepcji wolności i praw człowieka.

This article takes stock of the basic notions of Information Structure (IS). It first provides a general characterization of IS following Chafe (1976) within a communicative model of Common Ground (CG), which distinguishes between CG content and CG management. IS is concerned with those features of language that concern the local CG. It then defines and discusses the notions of Focus (as indicating alternatives) and its various uses, Givenness (as indicating that a denotation is already present in (...) the CG), and Topic (as specifying what an statement is about). It also proposes a new notion, Delimitation, which comprises contrastive topics and frame setters, and indicates that the current conversational move does not satisfy the local communicative needs totally. It also points out that the rhetorical structuring partly belongs to IS. (shrink)

The commons have emerged as a key notion and underlying experience of many efforts around the world to promote justice and democracy. A central question for political theories of the commons is whether the visions of social order and regimes of political economy they propose are complementary or opposed to public goods that are backed up by governmental coordination and compulsion. This essay argues that the post-Marxist view, which posits an inherent opposition between the commons as a sphere of inappropriable (...) usage and statist public infrastructure, is mistaken, because justice and democracy are not necessarily furthered by the institution of inappropriability. I articulate an alternative pluralist view based on James Tully’s work, which discloses the dynamic interplay between public and common modes of provision and enjoyment, and their civil and civic orientations respectively. Finally, the essay points to the Janus-faced character of the commons and stresses the co-constitutive role of public goods and social services for just and orderly social life while remaining attentive to the dialectic of empowerment and tutelage that marks provision by government.

The notion of common morality plays a prominent role in some of the most influential theories of biomedical ethics. Here, I focus on Beauchamp and Childress’s models in the fourth and fifth edition of Principles of Biomedical Ethics as well as on a revision that Beauchamp proposed in a recent article. Although there are significant differences in these works that require separate analysis, all include a role for common morality as starting point and normative framework for theory construction (...) in combination with a coherence theory of moral justification. I defend to some extent the existence and empirical significance of common morality, as delineated by Beauchamp and Childress in different versions, but criticize its normative role. It is neither convincing as a moral foundation nor well compatible with a standard coherentist justification. I suggest that the authors should give up the foundational account for a more modest account of common morality as resource of well-established moral insights and experiences, which have proved generally valid but neither sufficient nor infallible. Beauchamp’s latest proposal appears as a step in this direction; indeed, it may be the beginning of the end of his common-morality theory. (shrink)

This paper explores how national socialist aesthetics and semiotics are regimented within the Swedish Nazi milieu today. In order to treat fascism as contemporary ideology, the article applies intertextuality and provenance as analytical concepts in the analysis of how Nazism is re-emerging discursively. The analysis contributes unique insights, as the dataset consists of extremist discourse aimed at providing members of the most prominent Swedish Nazi movement with guidance on how to embody and express national socialism in their everyday lives. The (...) analysis reveals that common-sense notions about ‘a natural life’ and mainstream aesthetics concerning an outdoor lifestyle emerge as central expressions of a ‘natural’ and ‘healthy’ embodiment of national socialism. This aesthetic finds its ideological motive in opposition to a ‘sick’, ‘Jewish’ and ‘parasitical’ way of living. Mainstream notions are thus turned into vehicles for political extremism. (shrink)

We analyze common reasoning about admissibility in the strategic and extensive form of a game. We define a notion of sequential proper admissibility in the extensive form, and show that, in finite extensive games with perfect recall, the strategies that are consistent with common reasoning about sequential proper admissibility in the extensive form are exactly those that are consistent with common reasoning about admissibility in the strategic form representation of the game. Thus in such games the solution (...) given by common reasoning about admissibility does not depend on how the strategic situation is represented. We further explore the links between iterated admissibility and backward and forward induction. (shrink)

Notions of democracy and nationhood constitute the pivotal legacy of the American Revolution, but to understand their development one must move beyond a purely American context. Citizens of a Common Intellectual Homeland explores the simultaneous emergence of modern concepts of democracy and the nation on both sides of the Atlantic during the age of revolutions. Armin Mattes argues that in their origin the two concepts were indistinguishable because they arose from a common revolutionary impulse directed against the (...) prevailing hierarchical political and social order. The author shows how the reconceptualization of democracy and the nation, which resulted from this revolutionary impulse, received its decisive form from the French Revolution. Although the French Revolution was instrumental in redefining the two terms, however, neither were these changes confined to France, nor did the new meanings merely radiate from France to other countries. To illustrate the transatlantic emergence of these ideas, Mattes considers the works of pairs of prominent intellectual contemporaries--one in America and the other in Europe--each writing on a common topic. The thinkers and topics include Thomas Paine and Edmund Burke on the transatlantic revolutions, John Adams and Friedrich von Gentz on the mixed constitution, James Madison and Immanuel Kant on perpetual peace, and Thomas Jefferson and Destutt de Tracy on the nation. Mattes's approach highlights the significant impact that the French Revolution had on the evolution of thought in the period, demonstrating that the emergence and early development of modern concepts of democracy and the nation in America were intimately tied to revolutionary events and processes in the larger Atlantic world. Preparation of this volume has been supported by the Thomas Jefferson Foundation. Jeffersonian America. (shrink)

In the paper the relation between the standard probabilistic characterization of the common cause and Bell's notion of local causality will be investigated. It will be shown that the probabilistic common cause follows from local causality if one accepts, as Bell did, two assumptions concerning the common cause: first, the common cause is localized in the intersection of the past of the correlating events; second, it provides a complete specification of the `beables' of this intersection. However, (...) neither assumptions are a priori requirements. In the paper the logical role of these assumptions will be studied and it will be shown that only the second assumption is necessary for the derivation of the probabilistic common cause from local causality.

The Scottish Common Sense School of philosophy emerged during the Scottish Enlightenment of the second half of the eighteenth century. The School’s principal proponents were Thomas Reid, James Oswald, James Beattie and Dugald Stewart. They believed that we are all naturally implanted with an array of common sense intuitions and these intuitions are in fact the foundation of truth. Their approach dominated philosophical thought in Great Britain and the United States until the mid nineteenth century. In recent years (...) philosophers have renewed their appreciation of the notion of common sense. In particular, discussions of common sense intuitions are integral to contemporary epistemological foundationalism. Scottish Common Sense Philosophy: Sources and Origins is a 5-volume collection of writings by and about philosophers in the eighteenth-century Scottish Common Sense School. The writings by Thomas Reid and Dugald Stewart are readily available in recent editions and facsimile reprints so this series focuses on less accessible and less well-known items. Oswald’s Appeal appears here in print for the first time in any form since 1772. Volume 2 is the first reset printing of Beattie’s Essay in over 100 years, and is the only edition to contain annotations that trace the major changes that he made to the text. Almost all of the responses in volumes 3 and 4 appear here in print for the first time since their original publication. These include reviews, pamphlets and excerpts from books. Also included is previously unpublished discussion of Beattie’s Essay by Dugald Stewart. The final volume is a bibliography of around 80 Scottish philosophers from the early eighteenth century to the close of the nineteenth century. Unlike the 1932 bibliography of Scottish philosophers offered by T. E. Jessop, which selectively presents only the philosophical writings by the various Scottish philosophers, this volume attempts to catalogue all of the writings by these philosophers in all of their editions.

My Ph.D. dissertation written under the supervision of Prof. Tomasz Placek at the Institute of Philosophy of the Jagiellonian University in Kraków. In one of its most basic and informal shapes, the principle of the common cause states that any surprising correlation between two factors which are believed not to directly influence one another is due to their common cause. Here we will be concerned with a version od this idea which possesses a purely probabilistic formulation. It was (...) introduced, in the form of a general principle, by Hans Reichenbach in his posthumously published book "The Direction of Time". The central notion of the principle in Reichenbach's formulation, and of the current essay, is that of screening off: two correlated events are screened off by a third event if conditioning on the third event makes them probabilistically independent. Reichenbach's principle marks also the beginning of a new field of philosophy: namely, that of ``probabilistic causality''. For the most part, the current essay can be seen as an effort at checking how far one can go with the purely statistical notions revolving around Reichenbach's idea of common cause. In short, the answer is ``surprisingly far''; in some classes of probability spaces all correlations between ``interesting'' events possess explanations of such sort. However, this fact lends itself to opposing interpretations; more on that in the conclusion. Chapters 6 and 7 contain mathematical results concerning these issues. The screening-off condition requires an equality of a probabilistic nature to hold; chapter 8 is a short discussion of slightly weakened versions of the condition, which hold if the sides of the above mentioned equality differ to a small degree. In chapter 2, after some mathematical preliminaries, we study the various formulations of the principle which might be said to stem from the original idea of Reichenbach. We also examine a few of the most salient counterarguments, which undermine at least some of the formulations. Chapter 3 is of a formal nature, dealing with various probabilistic notions which can be thought of as generalizations of Reichenbach's concept of common cause. The next chapter concerns the relationship between the idea of common causal explanation and the Bell inequalities. In chapter 5 we briefly present the form of Reichenbach's principle which can be found in the field of representing causal structures by means of directed acyclic graphs. (shrink)

The aim of this paper is to analyze notions of common good and of the state in late 19th century British social liberalism and their relation to collective action of the citizens. The author shows that British social liberals argued for a type of state that uses top down strategy to encourage collective action in order to transform individuals into a socially responsible groups, i.e. good citizens. The paper focuses on philosophical works of F. H. Bradley, ethics of (...) T. H. Green and political philosophy of B. Bosanquet, analyzing their efforts to reconceptualize ideas of classical liberalism and utilitarian doctrine of the individual, society and the state in light of emerging influence of leftist social movements. The author argues that the works of British social liberals are a foundation of the state and society which will dominate liberalism in the second half of 20th century, i.e. the idea of the welfare state.
