Unlike the rationalism of the French Revolution, true liberalism has no quarrel with religion, and I can only deplore the militant and essentially illiberal antireligionism which animated so much of nineteenth-century Continental liberalism. ... What distinguishes the liberal from the conservative here is that, however profound his own spiritual beliefs, he will never regard himself as entitled to impose them on others and that for him the spiritual and the temporal are different sphere which ought not to be confused.

The social sciences, like much of biology but unlike most fields of the physical sciences, have to deal with structures of essential complexity, i.e. with structures whose characteristic properties can be exhibited only by models made up of relatively large numbers of variables.

It is no accident that on the whole there was more beauty and decency to be found in the life of the small peoples, and that among the large ones there was more happiness and content in proportion as they had avoided the deadly blight of centralization.

To undertake the direction of the economic life of people with widely divergent ideals and values is to assume responsibilities which commit one to the use of force; it is to assume a position where the best intentions cannot prevent one from being forced to act in a way which to some of those affected must appear highly immoral. This is true even if we assume the dominant power to be as idealistic and unselfish as we can possibly conceive. But how small is the likelihood that it will be unselfish, and how great are the temptations!

It is one of the most fatal illusions that, by substituting negotiations between states or organized groups for competition for markets or for raw materials, international friction would be reduced. This would merely put a contest of force in the place of what can only metaphorically be called the "struggle" of competition and would transfer to powerful and armed states, subject to no superior law, the rivalries which between individuals had to be decided without recourse to force.

The great aim of the struggle for liberty has been equality before the law.

There is all the difference in the world between treating people equally and attempting to make them equal.
