All life is problem solving

True ignorance is not the absence of knowledge, but the refusal to acquire it.

The growth of knowledge depends entirely upon disagreement.

In so far as a scientific statement speaks about reality, it must be falsifiable; and in so far as it is not falsifiable, it does not speak about reality.

The best thing that can happen to a human being us to find a problem, to fall in love with that problem, and to live trying to solve that problem, unless another problem even more lovable appears.

Ignorance is not a simple lack of knowledge but an active aversion to knowledge, the refusal to know, issuing from cowardice, pride, or laziness of mind.

I can't drink a wine if it has an ugly label.

I've got fans and letters from Israel, France Germany, Sweden, London, Africa. They all saying pretty much the same thing, 'Yo, we love you, we need you, put some more music out, please!'

I was lost til you were found, but I never knew how far down I was falling before I reached the bottom.

I can't say that I've fully achieved my dream yet. I'm just starting to evolve.

Petitions are ridiculous.

Purity of soul and impurity of body can go together.
