On the mountains of truth you can never climb in vain: either you will reach a point higher up today, or you will be training your powers so that you will be able to climb higher tomorrow.

It is better to understand a part of truth and apply it to our lives than to understand nothing at all and flounder helplessly in a vain attempt to pierce the mystery of existence.

When someone hides something behind a bush and looks for it again in the same place and finds it there as well, there is not much to praise in such seeking and finding. Yet this is how matters stand regarding seeking and finding truth within the realm of reason.

If I make up the definition of a mammal, and then, after inspecting a camel, declare "look, a mammal' I have indeed brought a truth to light in this way, but it is a truth of limited value.

The fervor about having the truth counts very little today in relation to that other fervor, more gentle and silent, to be sure, for seeking the truth, a search that does not tire of learning afresh and testing anew.

Here the ways of men part: if you wish to strive for peace of soul and pleasure, then believe; if you wish to be a devotee of truth, then inquire.
