多樣的情感形式誕生于身體的感觸經驗,因際遇不同,情感總在悲苦與快樂間變化流轉,這種情感的流變即是"情動"。本文從斯賓諾莎的相關論述出發,結合尼采、德勒茲等人的觀點,旨在探究情動與身體、力、欲望、生命之間的復雜關系。事實上,情動作為存在之力或活動之力的變化,表明了情感與身體的力量的密切關聯,重新勾勒了人作為情感主體的生存樣式,其中既有對笛卡爾身心二分的批評,也有與結構主義者、福柯和阿爾都塞的差別。在情動、權力意志、欲望機器的親密譜系中,身體和心靈并未彼此分離,生命之力盡管以各異的形式呈現,卻總是發出持續的呼喚:讓我們堅持一種快樂的唯物主義倫理學。

The diverse forms of feelings, which are born in the experience of bodily stirrings, vary from bitterness to happiness owning to distinct situations. This variation or flowage could be described by the notion of affect. This paper, combining the relevant expositions of Spinoza with the ideas of Nietzsche, Gilles Deleuze and others, tries to explore the complicated relation between affect, body, force, desire, and life. In fact, affect, as the flow of force or puissance, shows its close relation with the force of body and underlines the existential mode of man as an affective subject, in which, there are both the criticism of Descartes’ mind-body dualism and the divergence with the Structuralists, Louis Althusser and Michel Foucault. The genealogy of affect, will to power and desire machine shows that the body and mind are never separate from each other and even though appearing in various forms, the force of life always sends out a lasting call: hold to a happy materialistic ethics.
