Abstract

Our aim in this essay is to present some David Hume’s contributions on reasons for action’s debate. We tried to do this mainly from the discussions presented in the chapters “Of liberty and necessity”, from his An enquiry concerning human understanding, and “Of the general principles of morals” and “Concerning moral sentiment”, both from his An enquiry concerning the principles of morals. Starting from Bernard Williams' provocation in his description of what would be a “sub-Humean” model about reasons for action, we intend to present what the “properly Humean” model of understanding the subject would be. The efforts for this attempt were spent in three different ways, respectively concerning in to reconstruct the Humean argument. The relationships between feelings, sentiments, reason, actions, motivation for action and moral judgments are discussed, in the first section, while tributaries of the debate of the dispositions of the understanding about freedom and necessity that are related to Hume’s attempts to comprehend the human condition in its epistemological aspects. In the second and in the third sections, we seek to expose the possible understanding of the concepts mentioned above within the Humean framework to moral philosophy itself. From this, we can affirm that for Hume the reasons for action, that is, the elements that could be characterized as motivators for actions and behaviors can be said to reside ultimately in the subjectivity of the human condition and be originated from human sensitivity which is in turn constituted by passions, emotions, will, desires and moral sentiments.
