From early on, comparative philosophy has had on offer a high variety of goals, approaches and methodologies. Such high variety is still today a trademark of the discipline, and it is not uncommon of representatives of one camp in comparative philosophy to think of those in other camps as not really being about ‘comparative philosophy’. Much of the disagreement arguably has to do with methodological problems related to the concept of comparison and with the widely prevailing but unwarranted assumption that (...) comparative philosophy should be about comparing ‘culturally different philosophies’. This paper seeks to problematize this assumption by clarifying conceptually the notions of ‘comparative philosophy’ and of ‘comparison’, by showing the prevalence of the assumption in recent second-order discussions of methodology in comparative philosophy and its restraining implications in a randomly selected contribution of ‘Chinese philosophy’. At the end, a rallying call for a (self-)critical comparative philosophy is issued. (shrink)

Many philosophers have claimed that the intentional is normative. (This claim is the analogue, within the philosophy of mind, of the claim that is often made within the philosophy of language, that meaning is normative.) But what exactly does this claim mean? And what reason is there for believing it? In this paper, I shall first try to clarify the content of the claim that the intentional is normative. Then I shall examine a number of the arguments that philosophers have (...) advanced for this claim (and for the parallel claim that meaning is normative). As we shall see, many of these arguments are unsuccessful. However, I shall close by giving a sketch of what may be a successful argument for this claim. (shrink)

Mit beeindruckender Geschwindigkeit hat der Transhumanismus in akademischen Kreisen und den Medien immer mehr Aufmerksamkeit gewonnen. Er wird von angesehenen Denkern unterstützt. Die ihm zugrunde liegende Triebkraft, Technologie zum größtmöglichen Nutzen der Menschen zu nutzen, hat offenbar ihren Reiz. Dennoch begegnet ein beachtlicher Teil der Menschen dem Transhumanismus mit Skepsis, Abneigung, sogar Verachtung. Ein verwirrendes Phänomen.

Spirituality emerges in the function of culture to reinforce and yet redirect our genetic heritage. Our genes urge us to be concerned only for our own welfare, which can turn us to evil behaviors. Our religious traditions urge us to engage in behaviors of transkin altruism. These religious traditions have been selected for in the processes of natural selection. The challenge to spirituality is to discern the fundamental dynamics of the evolutionary processes, both genetic and cultural, that have created us (...) and to direct our behaviors in ways that can be beneficial to the entire natural system. Reason is not enough; we must also cultivate spiritual discernment in order to perceive the true nature of our situation and the best responses that are called for. The religious communities have the major responsibility for cultivating the spirituality that can achieve the most adequate discernment. (shrink)

Philosophers have long distinguished between practical and theoretical rationality. The first section of this chapter begins by discussing the ways in which this distinction was drawn by Aristotle and Kant; then it sketches what seems to be the general consensus today about how, at least roughly, the distinction should be drawn. The rest of this chapter explores what practical and theoretical rationality have in common: in the second section, several parallels between practical and theoretical rationality are outlined, and it is (...) argued that these parallels make it plausible that a unifying account of rationality can be given. Finally, in the third section, a number of such unifying accounts of practical and theoretical rationality are surveyed. These include accounts that are inspired in various ways by Hume and by the results of formal decision theory, as well as views that appeal to reasons and to the distinctive value of correct or appropriate attitudes.

A theory in natural science is a comprehensive formula or doctrine which describes and correlates in a unified abstract form of statement the general determining factors of some special group of natural facts. It is at once inclusive, realistic and understandable. If a theoretical statement holds good, the existence and characteristics of many individual events can be inferred deductively from it. It thus gives a logical basis for empirical fact. But it is based on experience of nature, and must conform (...) to the facts of nature; these are primary, and a valid theory, no matter how broad it may be, is to be considered as itself a statement of fact, i.e., a true description of some condition which has a real and stable existence in the natural world. In its scientific usage, the term “fact” refers primarily to some datum of experience having the special character of permanence or regular recurrence; this is why scientific facts are verifiable; in this respect they differ from the passing individual events of history. Any scientific theory presupposes the stability and unequivocality of the natural facts. Hence if a theory is sound, it furnishes a reliable basis for prediction, discovery and invention. Scientific or technological creation then becomes possible; modern engineering and medicine could never have become what they are without a background of theoretical physics and biology. Obviously any natural science must always have at its disposal an ample body of observational and experimental data, but in most cases the work of collecting and verifying these is carried out under the guidance of theory.

In considering this problem a distinction should first be made between its scientific and it philosophical aspects. The scientific problem is that of defining in exact understandable terms those conditions and factors which make possible the synthesis of the living organism from the simpler elements of the non-living environment, and also its maintenance in the adult state as a fully developed and autonomous organic individual. The problem as thus stated is one to be approached by methods of observation and experiment, (...) leading to verifiable results which are then expressed in systematic and intelligible form. The final statements or representations thus reached, the accepted scientific generalizations, inevitably take on a theoretical form, and as such are necessarily partial and abstract. Many of them, in fact, are to be regarded primarily as simplifications or models devised in the interest of clear representation or understanding. Their relation to concrete reality may range from attempts at exact portraiture to formulæ or diagrams having little more than heuristic significance. Any realistic philosophy of nature must always remember how incomplete and provisional are the theoretical conceptions of any natural science. (shrink)

In this reflection piece, Ralph Johnson provides an account of the development of informal logic and how it intersected with the Critical Thinking Movement. Section I is an account of the origins of what Johnson calls the “Informal Logic Initiative.” Section II discusses how the Informal Logic Initiative connected with the Critical Thinking Movement at the Sonoma State University Conferences starting in 1981. Section III discusses the relationship between logic and critical thinking. Section IV describes “The Network Problem,” which (...) emerged for Johnson in the mid-1980s – largely as a result of his experiences at critical thinking conferences, especially the Sonoma State conference. Section V expresses some concerns about the current status of critical thinking as an educational idea and about the Critical Thinking Movement. (shrink)

Biology is in a unique position among the natural sciences. It is not simply complex physics and chemistry, for living organisms have a psychological as well as a physical side. Even as physical systems their character is highly special, largely because their material substance is continually changing; perhaps it was from them that Heraclitus derived his idea that all is flow. The comparison with vortexes and candle flames is an old one. Wilhelm Ostwald included living organisms in his class of (...) “stationary systems”: they represent not a static but a kinetic equilibrium, what we now often call a “steady state”; there is a balance of constitutive and dissipative processes. Materials and energy converge to the living center, undergo there characteristic transformations, among which complex chemical and structural syntheses are conspicuous, and are again distributed at random to the surroundings. The living organism is thus the seat of a special type of physical and chemical activity found nowhere else in nature, and it is significant that this is associated with psychical activity—demonstrably in the higher organisms, by implication in the lower.

Robert Koch discovered the causal agents for tuberculosis, cholera, and anthrax. The 1905 Nobel Prize acknowledged Koch 's criteria for identifying the causal agent of an infectious disease. These criteria remain useful and the data reviewed below show that the cholinergic contributions to REM sleep control are confirmed by Koch 's postulates. [Hobson et al.].

This essay gives a new interpretation of some of the central ethical doctrines of Bishop Butler's Sermons -- in particular, of his claim that a review of the empirical facts of human nature shows that we have "an obligation to the practice of virtue", and of the precise claims that he makes about the relations between morality and self-interest.

Many philosophers think that internalism supports a noncognitivist account of normative judgments, according to which these judgments do not count as genuine beliefs, but rather as non-cognitive states of some kind. Such noncognitivist accounts of normative judgments naturally accompany an expressivist account of the meaning of normative statements. This chapter considers the prospects of such an expressivist theory, taking as its paradigm the most recent theory of Allan Gibbard. It is argued that this theory is vulnerable to a strengthened form (...) of the objection that P. T. Geach derived from the work of Frege. This makes it plausible that expressivist accounts face insuperable problems, and so that both expressivism and non-cognitivism should be rejected. (shrink)

Despite the enormous diversity in plant form, structure and growth environment across the seed‐bearing plants (angiosperms and gymnosperms), the chloroplast genome has, with few exceptions, remained remarkably conserved. This conservation suggests the existence of universal evolutionary selection pressures associated with photosynthesis—the primary function of chloroplasts. The stark exceptions to this conservation occur in parasitic angiosperms, which have escaped the dominant model by evolving the capacity to obtain some or all of their carbon (and nutrients) from their plant hosts. The consequence (...) of this evolution to parasitism is a relaxation of the evolutionary constraints associated with the need to maintain photosynthetic function, the very function that drove early stages of the ancient symbiotic relationship that produced the contemporary chloroplast. Extreme examples of reductionism among parasitic angiosperms reveals major alterations in chloroplast function with the loss of photosynthetic capacity and, with that, massive alterations in chloroplast genome content. This review highlights emerging patterns in reported gene loss and gene retention in the chloroplast genomes of parasitic plants. Some gene losses appear to occur in the early stages of parasitic evolution, even before the loss of photosynthetic capacity, like the chlororespiratory (ndh) genes. This contrasts with unexpected gene retentions, like that of the rbcL gene responsible for photosynthetic carbon dioxide fixation, and belies current understanding of gene function. The review relates gene retention to current knowledge of protein function and gene processing that has implications to broader aspects of genome conservation in organelles.
