In the seventeenth century, the concept of natural law was linked with that of “innate ideas”. Natural laws were said to be ideas imprinted by nature or by God on men's minds and were the very foundation of religion and morality. Locke's attack on innate ideas in the first book of his Essay Concerning Human Understanding is therefore considered to be an assault on natural law. Modern critics like Peter Laslett, W. von Leyden and Philip Abrams are of the opinion (...) that Locke's critique of innate ideas in the Essay cannot be reconciled with the concept of natural law in the Two Treatises of Government.
