There is, I conceive, no contradiction in believing that mind is at once the cause of matter and of the development of individualised human minds through the agency of matter.

What birds can have their bills more peculiarly formed than the ibis, the spoonbill, and the heron?

To expect the world to receive a new truth, or even an old truth, without challenging it, is to look for one of those miracles which do not occur.

Truth is born into this world only with pangs and tribulations, and every fresh truth is received unwillingly.

To the mass of mankind religion of some kind is a necessity.

To say that mind is a product or function of protoplasm, or of its molecular changes, is to use words to which we can attach no clear conception.

I am decidedly of the opinion that in very many instances we can trace such a necessary connexion, especially among birds, and often with more complete success than in the case which I have here attempted to explain.

I spent, as you know, a year and a half in a clergyman's family and heard almost every Tuesday the very best, most earnest and most impressive preacher it has ever been my fortune to meet with, but it produced no effect whatever on my mind.

It has been generally the custom of writers on natural history to take the habits and instincts of animals as the fixed point, and to consider their structure and organization as specially adapted to be in accordance with them.

On the spiritual theory, man consists essentially of a spiritual nature or mind intimately associated with a spiritual body or soul, both of which are developed in and by means of a material organism.

In all works on Natural History, we constantly find details of the marvellous adaptation of animals to their food, their habits, and the localities in which they are found.

I hold with Henry George, that at the back of every great social evil will be found a great political wrong.

I am thankful I can see much to admire in all religions.

Civilisation has ever accompanied emigration and conquest - the conflict of opinion, of religion, or of race.

There is, I conceive, no contradiction in believing that mind is at once the cause of matter and of the development of individualised human minds through the agency of matter.

What we need are not prohibitory marriage laws, but a reformed society, an educated public opinion which will teach individual duty in these matters.

But naturalists are now beginning to look beyond this, and to see that there must be some other principle regulating the infinitely varied forms of animal life.

As well might it be said that, because we are ignorant of the laws by which metals are produced and trees developed, we cannot know anything of the origin of steamships and railways.

The foregoing considerations lead us to the very important conclusion, that matter is essentially force, and nothing but force; that matter, as popularly understood, does not exist, and is, in fact, philosophically inconceivable.

In my solitude I have pondered much on the incomprehensible subjects of space, eternity, life and death.

I have since wandered among men of many races and many religions.

If this is not done, future ages will certainly look back upon us as a people so immersed in the pursuit of wealth as to be blind to higher considerations.

Modification of form is admitted to be a matter of time.

Nor should we exclude the possibility that Islamic terrorism may begin to make common cause with Western political extremists of the far Left and far Right.

We used to think that revolutions are the cause of change. Actually it is the other way around: change prepares the ground for revolution.

Our income are like our shoes; if too small, they gall and pinch us; but if too large, they cause us to stumble and trip.

The present contains nothing more than the past, and what is found in the effect was already in the cause.

To believe in a just law of cause and effect, carrying with it a punishment or a reward, is to believe in righteousness.

I wish I knew at 14 not to put much thought into what other people my age said to me, cause we were all looking for the answers. So I wish I knew that other people really don't know any more than you do!

One of the things that has always motivated me to write is the desire to get it out and look at it in an objective way, so that it doesn't cause me any serious pain by staying inside.

There are nuclear weapons in China, Iran, Korea and Pakistan. It wouldn't take much to send a couple of warheads off on this planet somewhere that would cause a lot of environmental damage, then if you have got someone who wants to retaliate you have real problems.

I never considered a difference of opinion in politics, in religion, in philosophy, as cause for withdrawing from a friend.

You have to not listen to the nay sayers because there will be many and often they'll be much more qualified than you and cause you to sort of doubt yourself.

A strong mind always hopes, and has always cause to hope.

While some no other cause for life can give, but a dull habitude to live.

The intelligence investigation under the leadership of Senator Church, which I know has helped cause this investigation by you, points out that the agencies did not disclose certain facts to us and that certain plots were going on.

I accept extinction as best explaining disjoined species. I see that the same cause must have reduced many species of great range to small, and that it may have reduced large genera to so small, and of families.

The probability that we may fail in the struggle ought not to deter us from the support of a cause we believe to be just.

You know, people want to honor me, and on the one hand I just don't want to be a poster child; but on the other, I want to do something classy and great - something where the residuals will go to the cause.

It is the cause, not the death, that makes the martyr.

I think that feeling that if one believed absolutely in any cause, then one must have the confidence, the self-certainty, to go through with that particular course of action.

The cause is hidden; the effect is visible to all.

If we are able to get inside the music and inhabit it convincingly enough, it will cause everyone to find each other in this new psychological space. And that's most exciting.

I hold that the mark of a genuine idea is that its possibility can be proved, either a priori by conceiving its cause or reason, or a posteriori when experience teaches us that it is in fact in nature.

I hope to stand firm enough to not go backward, and yet not go forward fast enough to wreck the country's cause.

I firmly believe that any man's finest hour, the greatest fulfillment of all that he holds dear, is that moment when he has worked his heart out in a good cause and lies exhausted on the field of battle - victorious.

We have indeed at the moment little cause for pride: as a profession we have made a mess of things.

No cause is left but the most ancient of all, the one, in fact, that from the beginning of our history has determined the very existence of politics, the cause of freedom versus tyranny.

The cause-effect sequences in our brains are just as determining, just as inescapable, as anywhere else in Nature.
