SUMMARY
The article suggests that the Kantian account of mental illnesses is part of his study of logic in an attempt to claim, above all, that they hinder the training of attention, which will later allow us to publicly pursue knowledge. To this, the author elucidates the epistemic place that Kant gives to attention (Aufmerksamkeit) in his transcendental, metaphysical, and anthropological remarks, given the important role it plays in the public elaboration of knowledge. Addressing the place that Kant gives to mental weaknesses and illnesses in his anthropology lessons, the article sheds light on some correlations between these pathologies and attention, considering that mental weaknesses, as well as, mental illnesses warp, or are caused by, the fragile attention with which we direct our thoughts. This permits to shed light on a Kantian ideal related to the sovereignty of our attention, understood as a condition of possibility of the individual autonomy.
