Résumé : Le fonctionnalisme est une solution populaire au problème espritcorps. Il a un certain nombre de versions. Nous en exposons certaines parmi les principales, en énumérant une partie de leurs caractéristiques les plus importantes ainsi que certains « bugs » qui les ont entachées. Nous présentons comment les différentes variantes sont liées. Nombreux ont été les pessimistes à propos des perspectives du fonctionnalisme, mais la plupart des critiques ne tiennent pas compte des dernières mises à jour. Nous finissons en suggé-rant une variante du fonctionnalisme qui fournit une description complète de l'esprit.Abstract: Functionalism is a popular solution to the mind-body problem.

We end by suggesting a version of functionalism that provides a complete account of the mind.The mind-body problem is the problem of how the mental relates to the physical. We know they are intimately involved: the physical affects the mental when our body is injured and we feel pain, or when we drink alcohol and feel intoxicated; the mental affects the physical when we decide to retrieve a book and reach for it, or when we perceive the signal to cross the street and begin walking.

While dualism is intuitively appealing, it faces such serious difficulties (how to account for the intimate connections between the mental and the physical, how the mental and the physical could possibly interact, etc.) that it's been mostly abandoned. The other option is monism, according to which the mental and the physical
