Against Innate Ideas I•John Locke: first of the 3 great British empiricists•Locke: what does it mean for an idea to be innate? That it be in the mind?•But for idea Pto be in the mind = one consciously knows P"No proposition can be said to be in the mind, which it never yet knew, which it never yet was conscious of" (Essay Concerning Human Understanding, Book I, Chapter II, Section 5, p. 61). •Locke’s test: Innate ideas must be ideas that one is conscious of. If one is not conscious of these ideas, then they are not innate.

Against Innate Ideas I•But there are no ideas or principles such that they are already in one’s mind from birth and one consciously knows them.•E.g.: “It is impossible for the same thing to be, and not to be.” •Locke: Babies don’t seem to know this consciously.“They are so far from being brought into the world with us, so remote from the thoughts of infancy and childhood, that I believe, upon examination it will be found that many grown men want them.” I am, and I am not.

Against Innate Ideas II•Indeed, what does Locke hold about babies in particular?•Locke: Babies’ minds are tabula rasa, i.e. blank slates•That explains how babies can gain knowledge by degrees •And how do they gain knowledge? From EXPERIENCE•Explains why babies like to use all their senses to gain knowledge•Think of babies eating their own ‘snot’!! And licking the ground etc.

Against Innate Ideas III•Locke: if there were such innate ideas, then they have to be “universally known and naturally agreed”so that they can be ”subjects of universal and undoubted truths” and not the “unavoidable occasion of perpetual uncerta
