I well knew that to propose something which would be called extreme, was the true way not to impede but to… — John Stuart Mill

The practical reformer has continually to demand that changes be made in things which are supported by powerful and widely-spread feelings, or to question the apparent necessity and indefeasibleness of established facts; and it is often an indispensable part of his argument to show, how these powerful feelings had their origin, and how those facts came to seem necessary and indefeasible. There is therefore a natural hostility between him and a philosophy which discourages the explanation of feelings and moral facts by circumstances and association, and prefers to treat them as ultimate elements of human nature; a philosophy which is addicted to holding up favorite doctrines as intuitive truths, and deems intuition to be the voice of Nature and of God, speaking with an authority higher than that of our reason. In particular, I have long felt that the prevailing tendency to regard all the marked distinctions of human character as innate, and in the main indelible, and to ignore the irresistible proofs that by far the greater part of those differences, whether between individuals, races, or sexes, are such as not only might but naturally would be produced by differences in circumstances, is one of the chief hindrances to the rational treatment of great social questions, and one of the greatest stumbling blocks to human improvement.

It is the character of the British people, or at least of the higher and middle classes who pass muster for the British people, that to induce them to approve of any change, it is necessary that they should look upon it as a middle course: they think every proposal extreme and violent unless they hear of some other proposal going still farther, upon which their antipathy to extreme views may discharge itself. So it proved in the present instance; my proposal was condemned, but any scheme for Irish Land reform, short of mine, came to be thought moderate by comparison.

[I]t might even be questioned if the various causes of deterioration which had been at work in the meanwhile, had not more than counterbalanced the tendencies to improvement. I had learnt from experience that many false opinions may be exchanged for true ones, without in the least altering the habits of mind of which false opinions are the result. The English public, for example, are quite as raw and undiscerning on subjects of political economy since the nation has been converted to free-trade, as they were before; and are still further from having acquired better habits of thought and feeling, or being in any way better fortified against error, on subjects of a more elevated character. For, though they have thrown off certain errors, the general discipline of their minds, intellectually and morally, is not altered. I am now convinced, that no great improvements in the lot of mankind are possible, until a great change takes place in the fundamental constitution of their modes of thought.
