The mind cannot foresee its own advance.

We must show that liberty is not merely one particular value but that it is the source and condition of most moral values. What a free society offers to the individual is much more than what he would be able to do if only he were free. We can therefore not fully appreciate the value of freedom until we know how a society of free men as a whole differs from one in which unfreedom prevails.

...the case for individual freedom rests largely on the recognition of the inevitable and universal ignorance of all of us concerning a great many of the factors on which the achievements of our ends and welfare depend.

I am still puzzled why those in the United States who truly believe in liberty should not only have allowed the left to appropriate this almost indispensable term but should even have assisted by beginning to use it themselves as a term of opprobrium. This seems to be particularly regrettable because of the consequent tendency of many true liberals to describe themselves as conservatives.

Freedom necessarily means that many things will be done which we do not like.

By the age of fifteen, I had convinced myself that nobody could give a reasonable explanation of what he meant by the word 'God' and that it was therefore as meaningless to assert a belief as to assert a disbelief in God. Though this, in a general way, has remained my position ever since, I have always avoided unnecessarily to offend other people holding religious belief by displaying my lack of such belief, or even stating my lack of belief, if I was not challenged.

I regard it in fact as the great advantage of the mathematical technique that it allows us to describe, by means of algebraic equations, the general character of a pattern even where we are ignorant of the numerical values which will determine its particular manifestation.
