Although a few scholars declared that there is no good reason to believe, and good reason not to believe, in the existence of innate ideas, the vast majority took for granted that God, in his infinite goodness and wisdom, has inscribed in human minds innate principles that constitute the foundation of knowledge, as well in practical as in theoretical matters. It was in opposition to the latter group, which included Descartes, leading Anglican divines, and the Cambridge Platonists, that Locke directed his attack upon innate ideas in the first book of the Essay. In the minds of those who weighed in on one side or the other, the importance of the controversy related to epistemological, moral, and religious doctrines. At the epistemological level, innatists (or, as I will also call them, nativists) held that all knowledge of the natural and supernatural world available to humans is based on fundamental “speculative” axioms, theoretical principles that neither require nor are capable of proof. These principles, such as the causal principle – that nothing comes from nothing – or the principle of non-contradiction – that nothing can both be and not be at the same time, were taken to be both universal and necessary, and hence impossible to derive from experience.
