John Stuart Mill Quotes
This is what writers mean when they say that the notion of cause involves the idea of necessity. If there be any meaning which confessedly belongs to the term necessity, it is unconditionalness. That which is necessary, that which must be, means that which will be, whatever supposition we may make in regard to all other things.

John Stuart Mill, usually cited as J. S. Mill, was an English philosopher, political economist, Member of Parliament, and civil servant. One of the most influential thinkers in the history of classical liberalism, he contributed widely to social theory, political theory, and political economy. Dubbed "the most influential English-speaking philosopher of the nineteenth century", he conceived of liberty as justifying the freedom of the individual in opposition to unlimited state and social control.
