In his Critique of pure reason Kant discusses two philosophical
doctrines of Aristotelian origin: the definition of truth as adaequatio
intellectus et rei and the theory of the transcendentals,
condensed in the formula quodlibet ens est unum, verum, bonum.
The Spanish philosopher Antonio Millán-Puelles has carried out,
in two of his books, an examination of the value of this Kantian
discussion. The aim of this paper is to comment on Millán-
Puelles’ analysis and to complete it in certain points, in order to
show its properly philosophical interest and its originality.
