Hermann Hesse said this quote

“ If only there were a dogma to believe in. Everything is contradictory, everything is tangential; there are no certainties anywhere. Everything can be interpreted one way and then again interpreted in the opposite sense. The whole of world history can be explained as development and progress and can also be seen as nothing but decadence and meaninglessness. Isn't there any truth? Is there no real and valid doctrine? Joseph Knect said to his Music Master there is truth, my boy. But the doctrine you desire, absolute perfect dogma that alone provides wisdom, does not exist. Nor should you long for a perfect doctrine, my friend rather, you should long for perfection in yourself. The deity is within you, not in ideas and books. Truth is lived not taught ”
