The present text follows three general objectives, which, at the same time, build its structure. Firstly, I would like to present and question Bernard Williams’ description of the virtue of accuracy. Secondly, I´ll try to complement Williams’ description by analyzing two dimensions of accuracy: care, on one side, and what I call “proximity to the problem”, on the other side. Related to that last issue, I add an excursus about writing. The third and last part of this article is an (...) attempt to relate the discussion about the so called virtues of truth —sincerity as well as accuracy— with the issue of self-deception. Specifically, I try to a) support Mele´s deflationary account of self-deception as motivationally biased belief, b) make an adjustment to this conception, and c) complement it with another aspect which has not received enough consideration in the discussion about self-deception, namely some beliefs we don´t generate or that manifest a high lack of accuracy.
