..every Man has a Property in his own Person. This no Body has any Right to but himself. The Labour of his Body, and the Work of his Hands, we may say, are properly his. .... The great and chief end therefore, of Mens uniting into Commonwealths, and putting themselves under Government, is the Preservation of their Property.
John LockeThe only thing we are naturally afraid of is pain, or loss of pleasure. And because these are not annexed to any shape, colour, or size of visible objects, we are frighted of none of them, till either we have felt pain from them, or have notions put into us that they will do us harm.
John LockeMany a good poetic vein is buried under a trade, and never produces any thing for want of improvement.
John LockeNobody is made anything by hearing of rules, or laying them up in his memory; practice must settle the habit of doing, without reflecting on the rule; and you may as well hope to make a good painter, or musician, extempore, by a lecture and instruction in the arts of music and painting, as a coherent thinker, or a strict reasoner, by a set of rules, showing him wherein right reasoning consists.
