The ethical component cannot be overemphasized, as "seeing things as they really are" entails an indispensable preliminary: "purification of the mind." This clarity of mind and concentrated awareness in turn begins with and must be sustained by moral conduct. The Visuddhimagga (Path of Purification), an early Buddhist manual compiled in the 4th century by Buddhagosha, lists the Buddha's "science" of inquiry as an interrelated three-step exercise of virtue, meditation, and insight. This is quite a different approach to knowledge than a modern-day scientist would presume or pursue. It is interesting that these ancient wisdom traditions considered moral purity as the absolute prerequisite of true knowledge, and that we today regard it as immaterial, if not downright irrelevant. Thus, fundamental and qualitatively different views of what constitutes knowledge and the acquisition of knowledge separate Buddhism and science.
