More quotes by Charles Darwin
The fact of evolution is the backbone of biology, and biology is thus in the peculiar position of being a science founded on an improved theory, is it then a science or faith?
Charles Darwin
In the long history of humankind (and animal kind, too) those who learned to collaborate and improvise most effectively have prevailed.
Charles Darwin
I am aware that the assumed instinctive belief in God has been used by many persons as an argument for his existence. The idea of a universal and beneficent Creator does not seem to arise in the mind of man, until he has been elevated by long-continued culture.
Charles Darwin
The Times is getting more detestable (but that is too weak word) than ever.
Charles Darwin
The main conclusion arrived at in this work, namely that man is descended from some lowly-organised form, will, I regret to think, be highly distasteful to many persons. But there can hardly be a doubt that we are descended from barbarians.
Charles Darwin
It may be doubted whether any character can be named which is distinctive of a race and is constant.
Charles Darwin
Not one great country can be named, from the polar regions in the north to New Zealand in the south, in which the aborigines do not tattoo themselves.
Charles Darwin
I am actually weary of telling people that I do not pretend to adduce [direct] evidence of one species changing into another, but I believe that this view is in the main correct, because so many phenomena can thus be grouped end explained.
Charles Darwin
The age-old and noble thought of 'I will lay down my life to save another,' is nothing more than cowardice.
Charles Darwin
I was a young man with uninformed ideas. I threw out queries, suggestions, wondering all the time over everything and to my astonishment the ideas took like wildfire. People made a religion of them.
Charles Darwin
I often had to run very quickly to be on time, and from being a fleet runner was generally successful but when in doubt I prayed earnestly to God to help me, and I well remember that I attributed my success to the prayers and not to my quick running, and marvelled how generally I was aided.
Charles Darwin
It is always advisable to perceive clearly our ignorance.
Charles Darwin
It seems to me absurd to doubt that a man may be an ardent Theist and an evolutionist. ... I have never been an atheist in the sense of denying the existence of a God.
Charles Darwin
...I believe there exists, & I feel within me, an instinct for the truth, or knowledge or discovery, of something of the same nature as the instinct of virtue, & that our having such an instinct is reason enough for scientific researches without any practical results ever ensuing from them.
Charles Darwin
If the misery of the poor be caused not by the laws of nature, but by our institutions, great is our sin.
Charles Darwin
Man is developed from an ovule, about 125th of an inch in diameter, which differs in no respect from the ovules of other animals.
Charles Darwin
Nothing can be more hopeless than to attempt to explain this similarity of pattern in members of the same class, by utility or by the doctrine of final causes.
Charles Darwin
Blushing is the most peculiar and the most human of all expressions. Monkeys redden from passion, but it would require an overwhelming amount of evidence to make us believe that any animal could blush.
Charles Darwin
I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection.
Charles Darwin
The most powerful natural species are those that adapt to environmental change without losing their fundamental identity which gives them their competitive advantage.
