The first step to get this noble and manly steadiness, is... carefully keep children from frights of all kinds, when they are young. ...Instances of … - John Locke

Should any one make so perverse an use of God's blessings poured on him with a liberal hand; should any one be cruel and uncharitable to that extremity; yet all this would not prove that propriety in land, even in this case, gave any authority over the persons of men, but only that compact might; since the authority of the rich proprietor, and the subjection of the needy beggar, began not from the possession of the lord, but the consent of the poor man, who preferred being his subject to starving. And the man he thus submits to, can pretend to no more power over him than he has consented to, upon compact.

For where is the man that has incontestable evidence of the truth of all that he holds, or of the falsehood of all he condemns; or can say that he has examined to the bottom all his own, or other men's opinions? The necessity of believing without knowledge, nay often upon very slight grounds, in this fleeting state of action and blindness we are in, should make us more busy and careful to inform ourselves than constrain others.

The only defense against the world is a thorough knowledge of it.
