And yet, for Seneca, in so far as we can ever attain wisdom, it is by learning not to aggravate the world’s obstinacy through our own responses, through spasms of rage, self-pity, anxiety, bitterness, self-righteousness and paranoia. A single idea recurs throughout his work: that we best endure those frustrations which we have prepared ourselves for and understand and are hurt most by those we least expected and cannot fathom. Philosophy must reconcile us to the true dimensions of reality, and so spare us, if not frustration itself, then at least its panoply of pernicious accompanying emotions.

-Botton, The Consolations of Philosophy, 81.
