“Even in earliest youth my fondest desire was to understand Nature, and thus to come closer to the truth; a truth that I was unable to discover either at school or in church.”

Boston Massacre Oration (1774)
Context: I have always, from my earliest youth, rejoiced in the felicity of my fellow-men; and have ever considered it as the indispensable able duty of every member of society to promote, as far as in him lies, the prosperity of every individual, but more especially of the community to which he belongs; and also, as a faithful subject of the State, to use his utmost endeavors to detect, and having detected, strenuously to oppose every traitorous plot which its enemies may devise for its destruction. Security to the persons and properties of the governed is so obviously the design and end of civil government, that to attempt a logical proof of it would be like burning tapers at noonday, to assist the sun in enlightening the world; and it cannot be either virtuous or honorable to attempt to support a government of which this is not the great and principal basis; and it is to the last degree vicious and infamous to attempt to support a government which manifestly tends to render the persons and properties of the governed insecure. Some boast of being friends to government; I am a friend to righteous government, to a government founded upon the principles of reason and justice; but I glory in publicly avowing my eternal enmity to tyranny.

The Future of Civilization (1938)
Context: I was brought up from my earliest youth to believe in the enormous importance of peace. I have often heard my father, the late Lord Salisbury, say that, though he did not see how it was possible under the then existing circumstances to avoid wars altogether, yet he had never been able to satisfy himself that they were in principle morally defensible.
Indeed, particularly in the latter part of his life, he made more than one speech in which he expressed the hope that, by some international combination, wars could in the future be prevented. He did not hesitate to express his belief that some such organization as we have since then attempted and erected in the League of Nations might furnish the solution of what he conceived to be the terrific evil of war.

The Captive Mind (1953)
Context: Undoubtedly, one comes closer to the truth when one sees history as the expression of the class struggle rather than a series of private quarrels among kings and nobles. But precisely because such an analysis of history comes closer to the truth, it is more dangerous. It gives the illusion of full knowledge; it supplies answers to all questions, answers which merely run around in a circle repeating a few formulas.

The Poet (1830)
Context: p>Thus truth was multiplied on truth, the world
Like one great garden show'd,
And thro' the wreaths of floating dark up-curl'd,
Rare sunrise flow'dAnd Freedom rear'd in that august sunrise
Her beautiful bold brow,
When rites and forms before his burning eyes
Melted like snow.</p
