Revolution is not a dinner party.
Revolutions have never lightened the burden of tyranny: they have only shifted it to another shoulder.
We have a lot of people revolutionizing the world because they've never had to present a working model.
Revolutions are not made by men in spectacles.
Revolution: in politics, an abrupt change in the form of misgovernment.
Many of the world's troubles are not due just to Russia or communism. They would be with us in any event because we live in an era of revolution--the revolution of rising expectations.
Revolutionary movements attract those who are not good enough for established institutions as well as those who are too good for them.
It is impossible to predict the time and progress of revolution. It is governed by its own more or less mysterious laws.
Revolutions are not trifles, but spring from trifles.
Make revolution a parent of settlement, and not a nursery of future revolutions.
The process of evolution may be described as differentiation of structure and integration of function. The more differentiated and specialized the parts, the more elaborate co-ordination is needed to create a well-balanced whole. The ultimate criterion of the value of a functional whole is the degree of its internal harmony or integratedness, whether the "functional whole" is a biological species or a civilization or an individual. A whole is defined by the pattern of relations between its parts, not by the sum of its parts; and a civilization is not defined by the sum of its science, technology, art and social organization, but by the total pattern which they form, and the degree of harmonious integration in that pattern.
The theory of evolution must be considered as a scientific theory, as theory, that is, proposed to explain or systemize a set of facts, and that no one has any claim to be considered as a serious rival to Darwin in the "discovery" of this theory who did not conduct his evolutionary studies upon a reasonably wide basis of facts. To have ideas, apercus, is not enough, and it is the overevalutation of such clever but uncontrolled guesses which is apt to produce the ludicrous fallacy of combination, in which fragments of the final theory are collected from widely scattered sources and are combined in such a way as to impugn the originality of him who was the first to see how such a synthesis was possible.
We must think of human progress, not as of something going on in the race in general, but as something going on in a small minority, perpetually beleaguered in a few walled towns. Now and then the horde of barbarians outside breaks through, and we have an armed effort to halt the process. That is, we have a Reformation, a French Revolution, a war for democracy, a Great Awakening. The minority is decimated and driven to cover. But a few survive- and a few are enough to carry on.
Evolution as such is no longer a theory for a modern author. It is as much a fact as that the earth revolves around the sun.
...anyone who writes about "Darwin's theory of evolution" in the singular, without segregating the theories of gradual evolution, common descent, speciation, and the mechanism of natural selection, will be quite unable to discuss the subject competently.
Nothing will benefit human health and increase chances for survival of life on Earth as much as the evolution to a vegetarian diet.
The influence of a beautiful, helpful character is contagious, and may revolutionize a whole town.
