A keystone to the history of ideas in the 17th century, in which Malebranche proceeds to unify the philosophy inherited from Descartes and Catholic dogmatism. To produce a physical effect outside the soul, a divine power is required, Malebranche denying the monism of physical causality. It includes chapters on the senses, imagination, understanding, passions... but also on science.
