This key thinker argues that though fundamentally rational, human nature is not fixed: it is forever progressing to a higher level:
-He saw liberty, for example, not just as a 'natural right' and an end to itself but as the engine of ongoing human development.
-As such, his human nature was never the 'finished article'; there was always room for improvement.
-He did not just want to liberate individuals as they were at present; instead, he pondered what individuals could become - a concept he termed 'individuality' and which has since been referred to as developmental individualism.
-He famously stated, it was 'better to be Socrates dissatisfied than a pig satisfied', while any support for liberty had to be 'grounded on the permanent interests of man as a progressive being'.
-With a view to clarifying tolerance, he divided human actions into 'self-regarding' and 'other regarding'.
-'self-regarding' human actions included religious worship or robust expression of personal views. These actions did not impinge on the freedom of others in society and therefore should be tolerated.
-'other regarding' human actions included violent or riotous behaviour, which clearly did 'harm' the freedom of others in society and therefore should not be tolerated by a liberal state.
-He stated, 'Over himself, over his own body and mind, the individual is sovereign'.
-He disagreed with Benthamite Utilitarianism which stated that human actions are so to gain pleasure or pain - for him, there were ‘higher and lower’ pleasures.
-He was concerned that during the mid-19th century, most would-be voters were ill-equipped to choose 'intelligent' representatives to act 'rationally' on their behalf.
-With that in mind, he argued that universal suffrage must be preceded by universal education, hoping this would promote developmental individualism - whereby there would be the advancement of individual potential, so as to produce a liberal consensus in society.
-This in turn would safeguard tolerance, reason and individualism, meanwhile, a vote would be withheld from the illiterate and unschooled, while those with a university education would receive more than one vote.
