| 摘 要： | Dualism is one of the views concerning the nature of mind. Arguments have been forwarded for and against dualism. Western philosophy lacks a clear distinction between soul and mind. Closely related to the concept of mind is the question of consciousness, a clear view of which has also eluded the westem thinkers. Jain philosophy describes ＂jiva＂ （soul） as the sentient substance, which is non-physical and not sense-perceptible; consciousness and ＂upayoga＂ （manifestation） are the differentia of ＂jiva＂. Consciousness manifests itself in many ways： intelligence, intuition, conation, bliss, perception （cognitive elements）, emotions, will, attitude and behavior, awareness of pleasure and pain. Jain distinguishes between soul and mind. The mind does not possess consciousness, which is the exclusive property of soul. Mind like soul is not permanent entity, and it exists only when consciousness manifests as thoughts, beliefs, desires, emotions and feelings. All these activities are influenced by karma, which is interface between soul and mind. Our existence is seen to be at three levels： soul, mind and body. Soul is the source of intelligence; mind （subtle body） is the executive and regulatory body and material body is the place of physical actions. A model of interactions between these three units is presented. The soul perceives and knows the external world through mind, so the perceptions made by soul are influenced by mind. The relationship between brain and mind is discussed. The brain is seen as the center for information storage and processing, its activity is regulated by mind, which in turn is conditioned by the soul. The conscious experience is made by the soul, not the mind. The Jain model of soul, mind and body avoids all objections raised against dualism, as interaction between soul and karma body （unconscious part of mind） is assumed to be based on parallelism, and that between mind and body is through radiations not violating the law of conservation of energy.
