The spiritual life to me has always meant just one thing: emotion. Emotion is the poetry of life.

One is never wounded by the love one gives, only by the love one expects.

The slope contains many wonders not found at the summit.

Philosophers console themselves with explanations.

The search for first causes is the ultimate wild goose chase.

When you separate thought from life, you get philosophy.

Logical positivism is philosophy from the neck up.

The questions philosophers ask are not so much meaningless as irrelevant.

No explanation is ever as good as not having one.

The truth is what you live through while you're looking for the truth.

Never confuse a hunger for knowledge with a thirst for truth.

In the universe, there are things that are known, and things that are unknown, and in between them, there are doors.

A few steps back is sometimes needed to find clarity in the confusion.

When Time is spent, Eternity begins.

You shouldn't get to live in society and give nothing back. People complain about their taxes, yet they do nothing for the community. That makes me furious.

The best advice I can give you about falling is to never land.

What is human behavior, except trying to prove that we're not animals?

The streets are full of admirable craftsmen, but so few practical dreamers.

The inner machinations of my mind are an enigma.

The present situation in physics is as if we know chess, but we don't know one or two rules.

You don't have to justify everything. Being pissed off is just absolutely okay.
