In The Gay Science, a philosophical work written in prose and verse, written in the form of aphorisms and published in 1882, Nietzsche mixes depth, evil and tenderness. It is considered by the author as the feeling of spiritual victory over the tyranny of evil, achieved by accepting life without rejecting pain. In its pages we can already sense the central themes of his works: the eternal return, the death of God, the superman and the will to power that he would later develop in Thus Spoke Zarathustra, considered the most important book of all those he wrote. It is a book full of joy, jubilation and happiness, although with expressions coming from pain. It places us on the threshold of Nietzschean thought, as he is still putting together what will constitute the peculiarity of his work. He had already traveled the deep valley of what has been unjustly considered to be his prophet: nihilism, so closely linked to the positivist belief in science and the metaphysical belief of Christianity. In this work, therefore, both of them will be the targets of his struggle against the splitting of the world, against “all metaphysics and physics that suppose an end… all predominantly aesthetic or religious longing for a separate world, a hereafter. The Gay Science will lead humanity towards a new destiny, putting its readers in a position to understand and assimilate its message, accompanying them to the highest heights. The title refers to the poetry of the Provençal troubadours, called Gay Science, gay knowledge, as a synthesis of song, chivalry and liberal spirit. Gay Knowledge aspires to be that Provençal knowledge, not burdened with metaphysics, capable of tragic depth and penetration. In some texts it is called not The Gay Science but The Gay Knowledge.
