Abstract
The transcendental relationship applied to the relationship soul and body in man: My goal is to analyse, first, the meaning of the category of the relationship, according to the concepts contained in the DM 47 over the predicamental and/or transcendental relationship category, applying it to the existing in the cosmos, the relationship between knowledge and the thing known and the compositum body-soul. Here I will make a reference to the similarity between Suarez and Kant about the postulate of the existence of God and the immortality of the human soul.
