In many computer applications we face the following situation: we are given set of objects which are characterized by means of some features like: temperature, height, weight etc., and we want to dene in terms of those features some concepts. For example we have a data le concerning patients suering from a certain disease. State of each patient is characterized by some symptoms like, for example: blood pressure, temperature etc. The question arises whether wa are able to dene this disease (...) in terms of avail- able symptoms. Notice that we identify here concept of a specic disease with a set of patients suering from this disease. Hence the denition of a disease depends upon specic example of a disease under consideration. This approach refers to inductive reasoning, when a concept is built upon the basis of a nite number of examples of this concept. More detailed discussion of problems considered here one { can nd in Pawlak , Pawlak and Or lowska and Pawlak. (shrink)

The author affirms the need for new evangelization. He claims however that it should focus on internal spiritual dimensions rather than simply on increasing the number of people brought up into evangelization. To evangelize others means to preach either inside a given church or outside it. The former turns out to make people live through the religion, they have been brought up, in the later should consist in preaching the gospel and some general ideas inherent to Christianity. Those who do (...) not belong to any church should have a free choice as for their religious commitments. The goal of evangelization in this sense is to overcome a fear of death, to help others to acquire deeper understanding of the Bible and to reach them how to be an active and self-effacing Christian.

Conceptual realism acknowledges the existence of abstract objects: theoretical realism acknowledges the existence of non-observable objects; whereas classical realism acknowledges the existence of observable objects. Similarly, temporal realism accepts the existence of future and past events along with present ones, and spatial realism accepts the events which occur there (else-where) as well as those that occur here. We dealt earlier with the three former kinds of realism and their opposites: nominalism, instrumentalism and (ontological) idealism [2]. This paper contains an examination (...) of the two latter forms of realism: temporal and spatial, and their counterparts: temporal and spatial irrealisms. Analogies and connections between these standpoints will be the focus of the paper. (shrink)

Giles of Orleans' philosophy evolved from an orthodox Christian interpretation of Aristotle to an Averroism; and his successive commentaries testify to this evolution: De generatione version I, De generatione version II, Physics version I and Physics version II. The first work presents orthodox Christian solutions, the second and the third testify to some Averroistic influences and the last is a clearly Averroistic commentary. Giles did not obey the regulation of 1272 which forbade the masters of the facilitas artium to discuss (...) theological problems. De generatione I discusses the question of world history as a chain of eternal reversions and solves it according to Christian orthodoxy. De generatione II and Physics I put forward the question whether accidents can exist without substance. The first work cites amply the Aristotelian solution and tries to reconcile it with a Christian understanding of the problem, whereas the second commentary accepts the opinion of Thomas Aquinas. In De generatione II and Physics II, Giles inquires whether an annihilated substance can reappear. The first commentary cites arguments for the negative answer, but it also gives a short declaratio fidei. The second commentary cites an and an orthodox solution, stating that one can solve the problem on two different planes - Christian or philosophical, both offering a different solution and unable to be reconciled. All three questions are listed in Tempier's Condemnation of 1277 - propositions 92, 196 and 215 - censuring heterodox answers. (shrink)

The paper presents an outline of two related space-time notions: the notion of location and the notion of extension. The first notion concerns only physical objects, the second notion referrs also to space-time objects. The approach to both notions is here non-metric of - strictly speaking - topological. The construction is carried out within the ontology of point-eventism. Hence two problems appear immediately: the problem of location of certain sets and the problem of their extension. The reason is that according (...) to the ontology of point-eventism all the physical as well as space-time objects - only point events excepted - are sets founded in such events. The author analyzes also the very relation between location and extension. (shrink)

The paper presents an analysis of two basic notions of the ontology of physics: the notion of physical entity; and the notion of spatio-temporal entity. The author claims that there are three types of physical as well as spatio-temporal entites: (i) objects; (ii) propertes; and (iii) relations. The philosophical background of the author's considerations is his conception of point-eventism.

The conceptual framework of the article consists of three basic terms: „quasi-simultaneity”, „co-location” and „genidentity” (with their negations). Within this framework the author formulates and discusses his main thesis: if two events are not genidentical, then they are either spatially or temporally separated. This thesis expresses the fact, that, loosely speaking, time and space have their common basis in difference of things.

The main task of the philosophy of value is seen to be the working out of a conceptual framework, within which evaluative reasoning could be analysed. Such conceptual framework does not have to rest on evaluative assumptions, but will necessarily have same normative impact, namely by marking our evaluations more conscious and coherent. The article outlines six methods, which could be used by the philosophy of value to justify the choice of values.

Immanuel Kant is the author of the project of “perpetual peace” as a concept for a global federation of states remaining in peaceful relations towards each other. According to the philosopher, in order for such a federation to be possible at some time in the future, individual states need to be institutions which respect their citizens’ right of self-determination. An additional necessary condition for the future implementation of “perpetual peace” is the appearance of at least one state with a republican (...) system of government. The German thinker saw that as the first step towards realising “perpetual peace”. According to Kant, “perpetual peace” is not only limited to the existence of a certain set of institutions, appropriate laws, or external relations among states and individual people. “Perpetual peace” chiefly demands that people internalise the following obligations: 1. peaceful conduct towards others; 2. hospitality; 3. fairness; 4. respect towards the self-determination of others; 5. self-sufficiency; 6. respecting the freedom of others; 7. refraining from actions which might raise distrust in others. Based on those requirements, the philosopher suggests that the fundamental condition for a future existence of “perpetual peace” is the proper moral education of people. (shrink)
