On my interpretation of Kant, feeling plays a central role in the mind: it has the distinct function of tracking and evaluating our activity in relation to ourselves and the world so as to orient us. In this article, I set out to defend this view against a number of objections raised by Melissa Merritt and Uri Eran. I conclude with some reflections on the fact that, despite being very different, Merritt and Eran’s respective views of Kantian feelings turn out to have something potentially problematic in common: they blur the boundary between feelings and other kinds of mental states.

The aim of this paper is to determine whether Kant's account of freedom fits with his theory of the human sciences. Several Kant scholars have recently acknowledged a tension between Kant's metaphysics and his works on anthropology in particular. Jacobs and Kain write that ‘Kant made his intentions quite clear: he proposed a pragmatic empirical anthropology. The problem is, as commentators have noted, that it is not at all clear how these declared intentions fit with some central claims of his critical philosophy.’ Wood acknowledges the unexpected nature of Kant's anthropological endeavours: ‘The pragmatic approach to anthropology serves to indicate the great distance separating Kantian anthropology from […] what Kant's metaphysical theory of freedom and nature might lead us to expect.’ Louden actually holds that ‘Kant did not satisfactorily address these issues, and in order for [him] to do so it will be necessary to offer conjectures that occasionally go beyond his texts.’

According to Kant, the opacity of human motivation takes two distinct forms – a psychological form: man ‘can never, even by the most strenuous self-examination, get entirely behind [his] covert incentives’ – and a social form: ‘everyone in our race finds it advisable to be on his guard, and not to reveal himself completely’. In other words, first, men's ‘interior’ (i.e. their intentions, motives, thoughts, etc.) cannot be entirely revealed to themselves and, second, they tend not to reveal their ‘interior’ to others. A number of Kant scholars have acknowledged the importance of the first form of opacity in Kant's thought and have attempted to draw out from it implications for moral deliberation and ethics in general. The aim of this paper is to examine the second, social form of opacity and draw out its anthropological implications, an issue that has been overlooked in the literature. To do so, I focus on Kant's contrast between men and beings that I would like to call ‘sincere aliens’. These sincere aliens are beings who have the opposite features of man's opacity, namely beings who cannot but reveal their ‘interior’ both to others and to themselves.
