How much truth does a spirit endure, how much truth does it dare?

The strength of a person's spirit would then be measured by how much 'truth' he could tolerate, or more precisely, to what extent he needs to have it diluted, disguised, sweetened, muted, falsified.

Nietzsche said that a man’s worth was determined by how much truth he could tolerate

The profundity of truth varies with the seeing power of the spirit which seeks it.

I speak truth, not so much as I would, but as much as I dare; and I dare a little the more as I grow older.

Truth is harder to bear than ignorance, and so ignorance is valued more—also because the status quo depends on it; but love depends on self-knowledge and self-knowledge depends on being able to bear the truth.

I speak the truth, not so much as I would, but as much as I dare; and I dare a little more as I grow older.

We can judge our progress by the courage of our questions and the depths of our answers, our willingness to embrace what is true rather than what feels good.

A very great deal more truth can become known than can be proven.

The true value of a man is not determined by his possession, supposed or real, of Truth, but rather by his sincere exertion to get to the Truth. It is not possession of the Truth, but rather the pursuit of Truth by which he extends his powers and in which his ever-growing perfectibility is to be found. Possession makes one passive, indolent, and proud. If God were to hold all Truth concealed in his right hand, and in his left only the steady and diligent drive for Truth, albeit with the proviso that I would always and forever err in the process, and offer me the choice, I would with all humility take the left hand, and say: Father, I will take this one—the pure Truth is for You alone.

We can judge our progress by the courage of our questions and our willingness to embrace what's true rather than what feels good.

The true measurement of a person's worth isn't what they say they believe in, but what they do in defense of those beliefs. If you're not acting on your beliefs, then they probably aren't real.
