The general objective of this paper is to substantiate the concept of vocation in the light of the dialogue between Amartya Sen's human capabilities approach and Kierkegaard's ethical proposal, presenting a parallel of possible contrasts. In this way, we review point by point the approaches that allow to weave arguments from the existential and ethical look of each one, under the premise of understanding vocation as an individual choice of each subject. To this end, as specific objectives to be developed, it is proposed to reconstruct the Kierkegaardian interpretation of vocation in the different stages of existence proposed by him; generating a frame of reference on vocation delimited to avoid ambiguities. With other similar concepts such as profession or other etymological interpretations of the same term. After that, we seek to raise points of connection between the Human Capabilities Approach (HCA) and the conceptualization of vocation in Kierkegaard, identifying how possible it is that the welfare referred to by Sen is in line with the approaches of the Dane and his way of understanding vocation.
