ABSTRACT
La·Mettrie is an early outstanding representative of the French materialism philosophy in 18 Centu-ry.And with his unique " man a machine" ideology,he demonstrated the unity of the relationship between body and mind,criticized the religious theology,scholasticism and the philosophy of previous physical and mental sepa-ration,which played an active role in enlightening people's thinking and laid an ideological foundation for the de-velopment of the capitalist society and economy at that time.He returned all of the life activities to mechanical movements or physical and chemical reactions,which objectively provided the theoretical foundation of philosophy for the generation of modern biomedical mode and also foreshadowed various problems emerging in the process of modern medical diagnosis and treatment activities.
