Nowadays there is a great enthusiasm for the Spinozan conception of the union of mind and body among modern researchers, such as Damasio. The fact that the Spinozan model has become very relevant is an opportunity to reflect on the impact and value of these references to Spinoza, which historians of philosophy eye with caution because they are all too often based on second-hand knowledge, and frequently distort the philosopher's thought. That is why it is crucial to reexamine the question of the mind-body relationship and its affective modalities in Spinoza from a philosophical angle and identify a model for interpreting it that is capable of informing contemporary debates.
