Children have as much mind to show that they are free, that their own good actions come from themselves, that they are absolute and independent, as any of the proudest of you grown men, think of them as you please.
John LockeThe thoughts that come often unsought, and, as it were, drop into the mind, are commonly the most valuable of any we have.
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 Locke
