Egzystencjalna metafizyka bytu w traktacie "De ente et essentia" Tomasza z Akwinu

Text De ente et essentia was written together with "De principis naturae" in Thomas’ first years of teaching activities and accounted philosophical “exercises” for the brothers at the convent of St. James in Paris. There is commonly noted, that Aquinas had already established the most important theses of his philosophy, the existential metaphysics of being above all, in which the act was the existence of this being, and the form with the matter constituted its essence. In this situation, the source of all existence, God appeared as only existence. Analysis of existential themes in "De ente et essentia" confirms these opinions. In later texts, especially in the "Summa Contra Gentiles", "Summa theologiae" and "Quaestiones disputatae", Thomas deepens his concepts; he introduces extended topic of transcendentals - property of being which manifest its existence. However, the bulk of his existential metaphysics of existence has been outlined already in "De ente et essentia", and it was never corrected in the basic theses.
