Milton Friedman -

The essence of political freedom is the absence of coercion of one man by his fellow men. The fundamental danger to political freedom is the concentration of power. The existence of a large measure of power in the hands of a relatively few individuals enables them to use it to coerce their fellow men. Preservation of freedom requires either the elimination of power where that is possible, or its dispersal where it cannot be eliminated.

George Orwell -

In our age there is no such thing as "keeping out of politics." All issues are political issues, and politics itself is a mass of lies, evasions, folly, hatred and schizophrenia.
