The end of all moral speculations is to teach us our duty; and, by proper representations of the deformity of vice and beauty of virtue, beget correspondent habits, and engage us to avoid the one, and embrace the other.
David HumeEvery disastrous accident alarms us, and sets us on enquiries concerning the principles whence it arose: Apprehensions spring up with regard to futurity: And the mind, sunk into diffidence, terror, and melancholy, has recourse to every method of appeasing those secret intelligent powers, on whom our fortune is supposed entirely to depend.
David Hume[The sceptic] must acknowledge, if he will acknowledge any thing, that all human life must perish, were his principles to prevail.All discourse, all action would immediately cease, and men remain in a total lethargy, till the necessities of nature, unsatisfied, put an end to their miserable existence.
David Hume
