Intellectuals first appeared in Europe as a distinct group in the sixteenth century in connection with the emergence of secular society and the concurrent advances of science. They were lay thinkers, often men of independent means, who approached the traditional questions of philosophy outside the framework of theology and the clerical establishment, which had previously enjoyed a monopoly on such speculation. Montaigne was a classic representative of the type which at the beginning of the seventeenth century came to be referred to as “intellectualist.” He reflected on life and human nature without giving any thought to the possibility that either could be changed. To humanists like him, man and the world in which he lived were givens. The task of philosophy was to help man acquire wisdom by coming to terms with that changeless reality. The supreme wisdom was to be true to one’s nature and so restrain one’s desires as to gain immunity to adversity, especially the inevitable prospect of death: in the words of Seneca, “to have the weaknesses of a man and the serenity of a god” (
It was in the early seventeenth century that a contrary trend emerged in European thought. Its stimulus came from the dramatic findings of astronomy and the other sciences. The discovery that it was possible to uncover nature’s secrets, and to use this knowledge to harness nature in the service of man, inevitably affected the way man came to view himself. The Copernican revolution displaced him and his world from the center of the universe. In one respect, this was a blow to man’s self-esteem; in another, it greatly enhanced it. By laying bare the laws governing the motions of celestial bodies, science elevated man to the status of a creature capable of penetrating the deepest mysteries of nature: the very same scientific knowledge which toppled him from the center of the universe gave him the power to become nature’s master. Francis Bacon was the earliest intellectual to grasp these implications of the scientific method and to treat knowledge—knowledge acquired through scientific observation and induction—as a means not only of gaining an understanding of the world but also of acting upon it. In his
Although scientific methodology progressively came to dominate Western thought, it took some time for man to view himself as an object of scientific inquiry. Seventeenth-century thought continued to adhere to the view inherited from antiquity and the Middle Ages, that man was composed of two discrete parts, body (
