CHAPTER XVIII
FREEDOM OF THOUGHT AND SPEECH[41]
If men's minds were as easily controlled as their tongues, every king would sit safely on his throne, and government by compulsion would cease; for every subject would shape his life according to the intentions of his rulers, and would esteem a thing true or false, good or evil, just or unjust, in obedience to their dictates. However, ... no man's mind can possibly lie wholly at the disposition of another, for no one can willingly transfer his natural right of free reason and judgment, or be compelled so to do. For this reason government which attempts to control minds is accounted tyrannical, and it is considered an abuse of sovereignty and a usurpation of the rights of subjects to seek to prescribe what shall be accepted as true, or rejected as false, or what opinions should actuate men in their worship of God. All these questions fall within a man's natural right, which he cannot abdicate even with his own consent.
I admit that the judgment can be biased in many ways, and to an almost incredible degree, so that while exempt from direct external control it may be so dependent on another man's words, that it may fitly be said to be ruled by him; but although this influence is carried to great lengths, it has never gone so far as to invalidate the statement that every man's understanding is his own, and that brains are as diverse as palates.
