John Locke,
Some Thoughts Concerning Education…
“ The only thing we naturally are 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 with none of them, till either we have felt pain from them, or have notions put into us that they will do us harm. The pleasant brightness and lustre of flame and fire so delights children, that at first they always desire to be handling of it: but when constant experience has convinced them, by the exquisite pain it has put them to, how cruel and unmerciful it is, they are afraid to touch it, and carefully avoid it. ”
