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.

The teachings of Francisco Suárez tend to have the queer quality of being at once transparent and unintelligible. An example of this is his theory of relations. It is clear that, according to Suárez, a categorical relation is both really and modally identical to its foundation; on the other hand, however, the relative denomination does not apply to the foundation unless the terminus of the relation actually exists. One may ask, then: given that the foundation exists but the terminus does not, is the relation actually there, or not? Suárez does not seem to have a clear answer to this query.

In Baroque scholasticism the medieval semantic theory of connotation as a property of terms, originally elaborated by Ockham and others, received an ontological application or re-interpretation in the context of the theory of relations. The main proponent of this ontologized “doctrina de connotatis” seems to have been Suárez. Subsequently, this doctrine was severely criticised by the Jesuits Pedro Hurtado de Mendoza and Rodrigo de Arriaga, but also by the “princeps Scotistarum” Bartholomeo Mastri; whereas another Scotist, John Punch, adopted a theory of relations close to this doctrine. The fates of the original semantic theory of connotation, the ontologized “doctrina de connotatis” and the broader context of the relevant discussions (especially the new res–modus ontology established around 1600) document the complexity of the history of scholastic ideas, irreducible to any simple paradigm (like that of the realism–nominalism strife).
