ACicero says that to philosophize is nothing else but to prepare for death. This is because study and contemplation draw our soul out of us to some extent and keep it busy outside the body; which is a sort of apprenticeship and semblance of death. Or else it is because all the wisdom and reasoning in the world boils down finally to this point: to teach us not to be afraid to die. In truth, either reason is a mockery, or it must aim solely at our contentment, and the sum of its labors must tend to make us live well and at our ease, as Holy Scripture says.
