This article puts in question some views on art, artwork, aesthetic attitude and aesthetic experience in order to propose the exercise of aesthetic rationality extending subjective capacity to guide the perception and understanding regarding the infinite possibilities of existence. The aesthetic rationality empowers subjects to conceive not only worlds reduced at referencial schemes, but from and about experience of presentification of what exists, of being, of effectual history and of derealization of established limits on traditional rationality forms. I postulate the idea of aesthetic experience as an opportunity for expansion and disclosure of subjectivity in that it represents an opening to the collection of examples that consist in art and life. The aesthetic attitude is a selfless attitude, an openness, a willingness not so much for the thing or event "in itself ", in what it has consistency, but the effects it can produce.
