 The second scholastic argument against occasionalism appeals to the purported fact that it is evident to the senses that creatures have causal power. For Malebranche, however, this argument is no more persuasive than the argument that bodies must have colors and tastes since our senses tell us that they do. As indicated above, Malebranche offers Cartesian grounds for thinking that the purpose of our sensations is not to reveal the true nature of the material world, but rather to indicate what is helpful or harmful to our body. Malebranche held that our attribution of causal powers to bodies manifests in particular an attachment to the body that is an effect of original sin. Due to this attachment, we take objects in the material world to be a cause of our happiness rather than God.
