This paper aims to establish a conception of humility which can be of use in nurturing interpersonal relationships of intrinsic value. The conception of humility asserted herein is a doxastic one that demands that an individual make an as-accurate-as-possible estimation of her knowledge, merits, and accomplishments in relation to others, in relation to the totality of knowledge, merits, and accomplishments, both actual and possible, of humankind, and in relation to an ideal. This paper asserts that humility consists of both a cognitive and an attitudinal component. The necessary cognitive component is an acknowledgment of the presence of great unknowable mysteries at play in every situation and every interaction between persons, which is further specified as the acknowledgment of the unknowability of the inner lives and consciousnesses of others. It is asserted that the attitudinal component of humility must result from the cognitive component and consists in keeping this acknowledgment consciously in mind in interactions in personal relationships and adopting actions and responses to others which are congruent with this acknowledgement. The conception of humility advocated in this paper takes points from the traditional Jewish conception of humility as presented by Daniel M. Nelson, a later account as formulated by the Jewish philosopher Martin Buber as well the more recent accounts of humility asserted by André Comte-Sponville, Julia Driver, G. Alex Sinha, J.L.A Garcia and Aaron Ben-Ze’ev.
