“I do not yet want to form a hypothesis to test, because as soon as you make a hypothesis, you become prejudiced.”

Your mind slides into a groove, and once it is in that groove, has difficulty noticing anything outside of it. During this time, my sense must be sharp; that is the main thing – to be sharp, yet open.

I already had a good start. As a teenager in rural Maine, after we came to America, I had learned hunting, fishing, and trapping in the wilderness.

My Maine mentors had long ago taught me to make home brew. I owned a rifle, and I’d already built a log cabin. The rest should be easy. I thought I’d give it a shot.

Trying to live in harmony with the dictates of nature is probably as inspirational as living in harmony with the Koran or the Bible. Perhaps it is also a timely undertaking.

Barry L. Jacobs and colleagues from the neuroscience program at Princeton University showed that when mice ran every day on an exercise wheel, they developed more brain cells and they learned faster than sedentary controls. I believe in mice.

Running is perhaps the most fundamental of all sports, and it is economically the least costly to perform.

Conditions are seldom ideal, and if one waits long enough for ideal conditions one is just making excuses.

The essential thing is to run period! And to do it for a long time and consistently and then everything will take care of itself.

For those that endure until spring, existence is reduced to its elegant essentials.

We are social animals. We like to feel a part of something of beauty and power that transcends our insignificance. It can be a religion, a political party, a ball club. Why not also Nature? I feel a strong identity with the world of living things.

As a consequence, it is the most democratic and most competitive of all sports because individual merit can prevail despite economic equality. It is a sport for everyone, the whole world over.

Edward Abbey said you must brew your own beer; kick in you Tee Vee; kill your own beef; build your cabin and piss off the front porch whenever you bloody well feel like it.

The very idea of “managing” a forest in the first place is oxymoronic, because a forest is an ecosystem that is by definition self-managing.

Spraying to kill trees and and raspberry bushes after a clear-cut merely looks unaesthetic for a short time, but tree plantations are deliberate ecodeath.

The psycho-physiological hypothesis is both inductively and deductively the sine qua non of the science of psychology.

We see what we want to see, and observation conforms to hypothesis.

But I should be very sorry if an interpretation founded on a most conjectural scientific hypothesis were to get fastened to the text in Genesis…

The rate of change of scientific hypothesis is naturally much more rapid than that of Biblical interpretations, so that if an interpretation is founded on such an hypothesis, it may help to keep the hypothesis above ground long after it ought to be buried and forgotten.

The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic or molecular constitution of matter.

Is evolution a theory, a system, or an hypothesis? It is much more: it is a general condition to which all theories, all hypotheses, all systems must bow and which they must satisfy henceforward if they are to be thinkable and true.

We know that communism is the right hypothesis.

But if you consider how abnormal their behavior is, then you are led to the hypothesis that almost all men are suffering from ‘testosterone poisoning.’
