Famous quotes containing the words security and/or concepts:
“Learned institutions ought to be favorite objects with every free people. They throw light over the public mind which is the best security against crafty and dangerous encroachments on the public liberty.”
—James Madison (1751–1836)
“Institutional psychiatry is a continuation of the Inquisition. All that has really changed is the vocabulary and the social style. The vocabulary conforms to the intellectual expectations of our age: it is a pseudo-medical jargon that parodies the concepts of science. The social style conforms to the political expectations of our age: it is a pseudo-liberal social movement that parodies the ideals of freedom and rationality.”
—Thomas Szasz (b. 1920)
