Abstract

Self-deception is a common phenomenon. Most traditional accounts of self-deception agree that self-deception is doxastic as it involves the acquisition of a false belief. Thus, it seems that any adequate doxastic theory of self-deception should be accompanied by a theory of belief acquisition. In this article, I argue that the mainstream doxastic view in the self-deception literature, namely motivationalism, presupposes a Cartesian theory of belief acquisition. I present and discuss the alternative Spinozan theory of belief acquisition and argue that self-deceptive beliefs are likely to be acquired in a Spinozan way. If this is correct, the causal route to self-deception proposed by motivationalists, which runs from evidence to belief, needs to be inverted. I offer a novel take on motivationalism based on Spinozan belief acquisition, which I call Spinozan self-deception. I discuss theoretical advantages of the novel view over motivationalism as well as some of the phenomena it may help explain.
