I believe there is no philosophical high-road in science, with epistemological signposts. No, we are in a jungle and find our way by trial and error, building our road behind us as we proceed.

Those who say that the study of science makes a man an atheist, must be rather silly people.

The belief that there is only one truth and that oneself is in possession of it seems to me the deepest root of all evil that is in the world.

Intellect distinguishes between the possible and the impossible; reason distinguishes between the sensible and the senseless. Even the possible can be senseless.

We need to make a world in which fewer children are born, and in which we take better care of them.

The belief in a single truth is the root cause for all evil in the world.

Physics as we know it will be over in six months.

My advice to those who which to learn the art of scientific prophesy is not to rely on abstract reason, but to decipher the secret language of Nature from Nature's documents: the facts of experience.

There are two objectionable types of believers: those who believe the incredible and those who believe that 'belief' must be discarded and replaced by 'the scientific method.

I am now convinced that theoretical physics is actually philosophy.

We have sought for firm ground and found none. The deeper we penetrate, the more restless becomes the universe; all is rushing about and vibrating in a wild dance.

One way to break up any kind of tension is good deep breathing.

...the number of saintly men has not yet risen to the level where the census makes them a separate statistical category.

You can't always be like 'sunshine and roses'. I like a little bit of darkness.

I ski very aggressively, and the angles that I create with my body are similar to some of the male racers.

See yourself reacting to threats, not by running away or evading them, but by meeting them, dealing with them, grappling with them in an aggressive intelligent manner.

Most young people are or will soon enough be workers. They can help to energize and radicalize the workers' movement. And what revolution has ever succeeded without youth?

Don't mess with me, lady. I've been drinking with skeletons.

I have no disagreement with the aims of anti-vivisectionists.

We are not saved by good works; we are saved for good works. The Christian lifestyle is to be a lifestyle of goodness.

Everything is soul and flowering.
