The true source of our sufferings has been our timidity.

... Turn our thoughts, in the next place, to the characters of learned men. The priesthood have, in all ancient nations, nearly monopolized learning. Read over again all the accounts we have of Hinduism, Chaldeans, Persians, Greeks, Romans, Celts, Teutons, we shall find that priests had all the knowledge, and really governed all mankind. Examine Mahometanism, trace Christianity from its first promulgation; knowledge has been almost exclusively confined to the clergy. And, even since the Reformation, when or where has existed a Protestant or dissenting sect who would tolerate a free inquiry? The blackest billingsgate, the most ungentlemanly insolence, the most yahoos brutality is patiently endured, countenanced, propagated, and applauded. But touch a solemn truth in collision with a dogma of a sect, though capable of the clearest proof, and you will soon find you have disturbed a nest, and the hornets will swarm about your legs and hands, and fly into your face and

We shall convince France and the world, that we are not a degraded people, humiliated under a colonial spirit of fear and a sense of inferiority, fitted to be the miserable instruments of foreign influence, and regardless of national honor, character, and interest.

When people talk of the freedom of writing, speaking or thinking I cannot choose but laugh. No such thing ever existed. No such thing now exists; but I hope it will exist. But it must be hundreds of years after you and I shall write and speak no more.

When writing the constitution for the Commonwealth of Massachusetts, John Adams wrote:I must judge for myself, but how can I judge, how can any man judge, unless his mind has been opened and enlarged by reading.
