Complementary to Newtonian science was the sensationalism of John Locke. Conceiving the mind as _tabula rasa_, discrediting innate ideas, Lockian psychology undermined such a theological dogma as total depravity--man's innate and inveterate malevolence--and hence was itself a kind of _tabula rasa_ on which later were written the optimistic opinions of those who credited man's capacity for altruism. If it remained for the French _philosophes_ to deify Reason, Locke honored it as the crowning experience of his sensational psychology.[i-9] Then, too, as Miss Lois Whitney has ably demonstrated, Lockian psychology "cleared the ground for either primitivism or a theory of progress."[i-10] In addition, his social compact theory, augmenting seventeenth-century liberalism, furnished the political theorists of the Enlightenment with "the principle of Consent"[i-11] in their antipathy for monarchial obscurantism. Locke has been described as the "originator of a psychology which provided democratic government with a scientific basis."[i-12] The full impact of Locke will be felt when philosophers deduce that if sensations and reflections are the product of outward stimuli--those of nature, society, and institutions--then to reform man one needs only to reform society and institutions, or remove to some tropical isle. We remember that the French Encyclopedists, for example, were motivated by their faith in the "indefinite malleability of human nature by education and institutions."[i-13] "With the possible exception of John Locke," C. A. Moore observes, "Shaftesbury was more generally known in the mid-century than any other English philosopher."[i-14] Shaftesbury's a priori "virtuoso theory of benevolence" may be viewed as complementary to Locke's psychology to the extent that both have within them the implication that through education and reform man may become perfectible. Both tend to undermine social, political, and religious authoritarianism. Shaftesbury's insistence upon man's innate altruism and compassion, coupled with the deistic and rationalistic divorce between theology and morality, resulted in the dogma that the most acceptable service to God is expressed in kindness to God's other children and helped to motivate the rise of humanitarianism.
