Kant’s Transcendental Theory of Moral Psychology Within Sellars’ Manifest Image

The paper in general investigates Kant’s transcendental theory of moral psychology in its relation to Sellarsian characterization of origin of normativity with respect to the preconditions of a complete conception of humans and their actions. The complete conception of humans and their actions is a conception in which we are able to account for free human in general and for his free will in particular in accordance with the natural law. I argue that Sellars’ manifest and scientific images of a person on the one hand and Kant’s empirical and intelligible character on the other hand has similar accounts for acquiring the knowledge of the source of our normative assessments. In both it is considered that manifest or empirical conception of a person within nature in general fails to provide a deductive procedure from which one can derive the complete conception of a person as a free being in itself. I further argue that any set of procedure for identifying the source of normativity and of our normative assessments cannot be provided from an ontologically oriented perspective in which we aim at establishing a naturalistic model of normativity- a model where accurate descriptions and true explanations of causal relations in the world of appearances can allow us to make sense the blameworthiness of the moral agent as the normative force applied on his actions.
