“There have been, and may be again, great individual thinkers, in a general atmosphere of mental slavery.”

“No one can be a great thinker who does not recognize that as a thinker it is his first duty to follow his intellect to whatever conclusions it may lead.”

“John Stuart Mill (20 May 1806 – 8 May 1873), English philosopher, political theorist, political economist, civil servant and Member of Parliament, was an influential liberal thinker of the 19th century whose works on liberty justified freedom of the individual in opposition to unlimited state control. He was an exponent of utilitarianism, an ethical theory developed by Jeremy Bentham, although his conception of it was very different from Bentham's. He clearly set forth the premises of the scientific method.”

“The worth of a State, in the long run, is the worth of the individuals composing it; and a State which postpones the interests of their mental expansion and elevation to a little more of administrative skill, or of that semblance of it which practice gives in the details of business; a State which dwarfs its men. In order that they may be more docile instruments in its hands even for beneficial purposes--will find that with small men no great thing can really be accomplished; and that the perfection of machinery to which it has sacrificed everything will in the end avail it nothing, for want of the vital power which, in order that the machine might work more smoothly, it has preferred to banish.”

“Even despotism does not produce its worst effects, so long as individuality exists under it; and whatever crushes individuality is despotism, by whatever name it may be called, and whether it professes to be enforcing the will of God or the injunctions of men.”

“In this age, the mere example of non-conformity, the mere refusal to bend the knee to custom, is itself a service. Precisely because the tyranny of opinion is such as to make eccentricity a reproach, it is desirable, in order to break through that tyranny, that people should be eccentric. Eccentricity has always abounded when and where strength of character has abounded; and the amount of eccentricity in a society has generally been proportional to the amount of genius, mental vigor, and moral courage which it contained. That so few now dare to be eccentric, marks the chief danger of the time.”

“Those only are happy .... who have their minds fixed on some object other than their own happiness, "a crisis in my mental history”
