Abstract: Traditional philosophy represented by Aristotle equals practice to moral practice. As a result， technological practice is excluded from human beings practical activities. Although Kant clearly distinguishes technological practice from moral practice and reveals that they follow some universal rules， he eventually fails to unify the two. Hegel analyzes human beings entire practice by integrating moral practice and technological practice; however， he replaces mankinds perceptual practice with abstract rationality， which is still confined to the pattern of traditional philosophy. Based on the humans realistic existence， Karl Marx regards technological practice as a fundamental form of practice and affirms its basic status in human beings practical activities. Therefore， he establishes a holistic view of practice from the perspective of dialectical materialism and fulfills a real unification of technical practice and moral practice， and theory and practice.

Key words: technological practice, moral practice, western philosophy, Karl Marx
