This article attempts to clarify Nietzsche’s concept of gaya scienza and the type of philosophical questions it raises in relation to life, and whether it is a denial of it with pure reason, or acknowledging it with ‘free thinking’. The essence of the philosophy of life with Nietzsche is the sum of critical answers that put into question the will of knowledge and the will of truth. Its goal is to confirm the growing philosophical ties he has with knowledge and life. Both of them pay them service to man in terms of the lifestyle and the type of knowledge that goes beyond the classical abstraction of man’s image. Freethinking will occupy the most important place; an illustration of this is the ‘wise reason’ path, which critically ventures into dogma, itself weakened by the vital action similar to ‘a hammer’s beats’. Thus, the acting mind with a critical sense raises the questions of man who values himself beyond good and evil.
