Education makes a man a more intelligent shoemaker, if that be his occupation, but not by teaching him how to make shoes; it does so by the mental exercise it gives, and the habits it impresses.

A people may prefer a free government, but if by momentary discouragement or temporary panic, or a fit of enthusiasm for an individual, they can be induced to lay their liberties at the feet of even a great man, or trust him with powers to subvert their institutions, in all these cases they are unfit for liberty.

If it were felt that the free development of individuality is one of the leading essentials of well-being; that it is not only a coordinate element with all that is designated by the terms civilisation, instruction, education, culture, but is itself a necessary part and condition of all those things; there would be no danger that liberty should be undervalued.

...it is not only the general principles of justice that are infringed, or at least set aside, by the exclusion of women, merely as women, from any share in the representation; that exclusion is also repugnant to the particular principles of the British Constitution. It violates one of the oldest of our constitutional maxims...that taxation and representation should be co-extensive. Do not women pay taxes?

He must be able to hear them [the counter arguments] from persons who actually believe them; who defend them in earnest, and do their very utmost for them. He must know them in their most plausible and persuasive form; he must feel the whole force of the difficulty which the true view of the subject has to encounter and dispose of; else he will never really possess himself of the portion of truth which meets and removes that difficulty.

Not the violent conflict between parts of the truth, but the quiet suppression of half of it, is the formidable evil; there is always hope when people are forced to listen to both sides; it is when they attend to only one that errors harden into prejudices, and truth itself ceases to have the effect of truth, by being exaggerated into falsehood.

The application of algebra to geometry ... has immortalized the name of Descartes, and constitutes the greatest single step ever made in the progress of the exact sciences.
