‘The child certainly knows that the nurse that feeds it is neither the cat it plays with, nor the blackamoor it is afraid of: that the wormseed or mustard it refuses is not the apple or sugar it cries for; this it is certainly and undoubtedly assured of: but will any one say it is by virtue of this principle, _That it is impossible for the same thing to be and not to be_, that it so firmly assents to these and other parts of its knowledge? Or that the child has any notion or apprehension of that proposition at an age, wherein yet, it is plain, it knows a great many other truths? He that will say, children join these several abstract speculations with their sucking bottles and their rattles, may perhaps with justice be thought to have more passion and zeal for his opinion, but less sincerity and truth than one of that age. Though therefore there be several general propositions that meet with constant and ready assent as soon as proposed to men grown up, who have attained the use of more general and abstract ideas, and names standing for them, yet they not being to be found in those of tender years, who nevertheless know other things, they cannot pretend to universal assent of intelligent persons, and so by no means can be supposed innate: it being impossible, that any truth which is innate (if there were any such) should be unknown, at least to any one who knows any thing else. Since if they are innate truths, they must be innate thoughts; there being nothing a truth in the mind which it has never thought on.
