The aim of the article is twofold: to document how what the author labels the “Principle of Reference” – viz. the claim that that which is not cannot be referred to – inspires both actualist and possibilist philosophical conceptions in the analytic tradition as well as in scholasticism, and to show how Duns Scotus’s rejection of the Principle allows us to see that there are two distinct and logically independent meanings of the actualism–possibilism distinction: viz. metaphysical actualism/…possibilism, and semantic actualism/possibilism. By way of an appendix, the author off ers some critical remarks on recent Czecho-Slovak debates about the ontological status of non-existents.

The purpose of this review article is to offer a criticism of the interpretation of Duns Scotus’s conception of intelligible being that has been proposed by Michael Renemann in his book Gedanken als Wirkursachen. In the first place, the author shows that according to Scotus, for God “to produce a thing in intelligible being” and “to conceive a thing” amounts to altogether one and the same act. Esse intelligibile therefore does not have “priority of nature” with respect to “esse intellectum” or “esse repraesentatum”, contrary to Renemann’s interpretation. The distinction between Scotus’s second and third “instants of nature” consists in something else, then: the relation of reason, of which Scotus says that it is produced in the third instant, is not the relation of being actually conceived (first, because actual intellection comes already in the second instant, and second, because divine intellection, being the measure of the conceived objects, is not relative bud absolute) but it is a relation of comparison, viz. of an image to its exemplar. Next, the author shows how a misreading of two passages of Scotus’s Ordinatio misled both the Vatican editors and Renemann to create the chimaera of “verum esse secundum quid”. By way of a conclusion the author argues that Scotus’s doctrine of “esse intelligibile” does not make him any less a direct realist than Suárez, his position being quite plausible even from the point of view of common sense

The article explains the notion of univocity in line with the mature Scotistic doctrine, which plays so crucial a role in the Scotistic rejection of analogy as a middle ground between univocity and pure equivocity. Since univocity of a concept is found to consist in its perfect unity, and the perfect unity of a concept is achieved by means of perfect abstraction, the notion of this so-called abstraction by precision is made clear and contrasted with the so-called abstraction by confusion, by means of which analogical concepts are supposed to be formed by the Thomists.

This discussion article is a critique of the theory of “rational compatibilism”, as presented in D. Peroutka’s eponymous article. The author raises the following nine objections against Peroutka’s conception: (1) Peroutka’s notion of liberty is ill-defined; (2) Peroutka’s argument “from growing probability” suffers from the confusion of logical and epistemic probability; (3) the charge of “irrationality” raised against the libertarian analysis of choice is either unsubstantiated or innocuous; (4) assigning the determining force to a final (rather than efficient) cause makes no difference with regard to freedom; (5) it is inexplicable in Peroutka’s conception why only a rational (as opposed to sensual) good can determine the will in a “compatibilist” way, i.e. without thereby compromising freedom; (6) Peroutka’s conception reduces “libertarian” situations to “perplexed” or “dilemmatic” situations, and so reduces all moral evil to evil “from ignorance”, leaving no room for evil “from weakness” and “from malice”; (7) the “asymmetry” in Peroutka’s conception (only evil acts have to be libertarian) only arises because the possibility of superrogatory acts has been ignored; (8) Peroutka’s conception turns libertarian freedom into an unjustifiable evil; and finally, (9) in his reply to Sartre Peroutka upholds Sartre’s proton pseudos: viz. the confusion of logical and deontic modality (viz. necessity and obligation). In an appendix the author shows that although Peroutka’s conception of rational compatibilism shares some points with Aquinas’s theory, as a whole it cannot be ascribed to him.

Saul Kripke denies that the reference of a proper name is mediated through a sense (an intension, a concept), and claims that it has to be immediate for „rigidity“ of a proper name to be saved. On the other hand, the version of the Identity Theory of predication according to which predication is characterised as intentional identification of the conceptual content of the predicate with the object represented by the subject-concept requires that there be a concept (sense of the term) at the places both of the subject and of the predicate. This paper is an attempt to propose a conception that purports to maintain the Identity Theory of predication with its demand for proper names to have senses and respond to Kripkean arguments while retaining the rigidity of proper names. Two main theses are defended: 1) Whether a term refers rigidly or non-rigidly does not depend on the nature of the term (i. e. whether it is a name or a description), but on the intention of the speaker/writer. Consequently, both names and descriptions can be used both rigidly and non-rigidly. 2) There is a „minimal sense“ to any proper name which can generaly be described as follows: „the person who has been given the name so-and-so“. The expression „has been given the name“ describes a „relation of reason“, which must be strictly distinguished from the relation of reference of the name, in order to avoid a vicious circle in reference determination, something against which Kripke warned.

Conceptual atomism is a doctrine deeply rooted in the tradition of western thought. It originated with Aristotle, was present in the entire Aristotelian tradition and came to its most pure expression in the work of Leibniz. However, ab initio this doctrine suffered from certain difficulty labelled traditionally “aporia generis”, namely the problem of how it is possible to reconcile the absolute simplicity of the primitive concepts (or ultimate differentiae) with the existence of transcendental concepts, that is, concepts necessarily included in every concept. In this paper the entire problem is subject to an analysis and a solution is suggested, based on a distinction between two different kinds of conceptual containment: the primitive concepts do not contain the transcendentals formally, that is, as constituents thatcan be revealed by means of definitional analysis, but they nevertheless do contain them virtually, that is, they strictly imply them. It is noted that the germ of this solution is already present in Aristotle.

P. Sousedík and D. Svoboda, in their paper “Různá pojetí matematiky u vybraných autorů od antiky po raný novověk: Je matematika teoretická věda nebo pouhá technika?”, proposed an interpretation of Aquinas’s understanding of the nature of mathematics which the author regards as unsatisfactory. The purpose of this review article is to point out its problems and to suggest in its stead an adequate interpretation of Aquinas’s mind, on the basis of a detailed analysis of his texts. The author shows that Aquinas was by no means an instrumentalist in mathematics but considered mathematical truths to be directly applicable to “physical matter”. Such an application takes place in sciences like astronomy, harmonics or optics, which, although sometimes subsumed under mathematics broadly conceived, nevertheless form a special category qua the so-called “middle sciences” (viz. situated between mathematics and physics) and are thus no true species of mathematics. The fact that these sciences are also regarded as “arts” does not preclude their scientific character at all, since the two categories are not mutually exclusive, according to St. Thomas.
