I have hardly ever known a mathematician who was capable of reasoning.

All knowledge or form conception is evoked through the medium of the eye, either in response to disturbances directly received on the retina or to their fainter secondary effects and reverberations. Other sense organs can only call forth feelings which have no reality of existence and of which no conception can be formed.

When I am getting ready to reason with a man, I spend one-third of my time thinking about myself and what I am going to say and two-thirds about him and what he is going to say.

Atoms are very special: they like certain particular partners, certain particular directions, and so on. It is the job of physics to analyze why each one wants what it wants.

Wisdom oft times consists of knowing what to do next.

There are in fact two things, science and opinion; the former begets knowledge, the latter ignorance.

It is a good thing for an uneducated man to read books of quotations.

We dance round in a ring and suppose, but the secret sits in the middle and knows.

As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value than a much smaller amount if you have not thought it over for yourself.

You can know or not know how a car runs and still enjoy riding in a car.

As commanders and staff officers, we are coaches and sentries for our units: how can we coach anything if we don’t know a hell of a lot more than just the TTPs?

The trouble with our Liberal friends is not that they’re ignorant; it’s just that they know so much that isn’t so.

It’s not a coincidence that in the Scriptures, poverty is mentioned more than 2,100 times. It’s not an accident. That’s a lot of air time, 2,100 mentions.

No group and no government can properly prescribe precisely what should constitute the body of knowledge with which true education is concerned.

There is no excellent beauty that hath not some strangeness in the proportion.

Religion and science are the two conjugated faces or phases of one and the same complete act of knowledge – the only one which can embrace the past and future of evolution and so contemplate, measure and fulfil them.

Reputation is an idle and most false imposition; oft got without merit, and lost without deserving.

Science is the father of knowledge, but opinion breeds ignorance.

A man who has never gone to school may steal from a freight car; but if he has a university education, he may steal the whole railroad.

I think that in the discussion of natural problems we ought to begin not with the Scriptures, but with experiments, and demonstrations.

There are worse crimes than burning books. One of them is not reading them.

His priority did not seem to be to teach them what he knew, but rather to impress upon them that nothing, not even… knowledge, was foolproof.

Faith is a knowledge within the heart, beyond the reach of proof.

Every formula of every religion has in this age of reason, to submit to the acid test of reason and universal assent.

People who know little are usually great talkers, while men who know much say little.

The Cuban model doesn’t even work for us anymore.

Cobb is a prick. But he sure can hit. God Almighty, that man can hit.

There is a single light of science, and to brighten it anywhere is to brighten it everywhere.

Men who wish to know about the world must learn about it in its particular details.

True knowledge exists in knowing that you know nothing.

The very phrase ‚foreign affairs‘ makes an Englishman convinced that I am about to treat of subjects with which he has no concern.

If all the economists were laid end to end, they’d never reach a conclusion.

Knowledge about life is one thing; effective occupation of a place in life, with its dynamic currents passing through your being, is another.

The work of science is to substitute facts for appearances, and demonstrations for impressions.

Mistakes are, after all, the foundations of truth, and if a man does not know what a thing is, it is at least an increase in knowledge if he knows what it is not.

More people should read books. It’s the most concentrated experience you can have.

Men are born ignorant, not stupid. They are made stupid by education.

All that I know about my life, it seems, I have learned in books.

It is paradoxical, yet true, to say, that the more we know, the more ignorant we become in the absolute sense, for it is only through enlightenment that we become conscious of our limitations. Precisely one of the most gratifying results of intellectual evolution is the continuous opening up of new and greater prospects.

Knowledge of what is does not open the door directly to what should be.

I believe the Republicans have never thought that democracy was anything but a tribal myth.

The ‚free-floating intellectual‘ may occupy himself with problems because of their inherent interest and importance, perhaps to little effect.

The desire of excessive power caused the angels to fall; the desire of knowledge caused men to fall.

No one’s policing their own minds more than an author. You spend a lot of time in your own head analysing what you think about things, and a philosophy comes.

Thinking fragments reality – it cuts it up into conceptual bits and pieces.

Dispassionate objectivity is itself a passion, for the real and for the truth.

Facts do not speak for themselves. They speak for or against competing theories. Facts divorced from theories or visions are mere isolated curiosities.
