Habit may lead us to belief and expectation but not to the knowledge, and still less to the understanding, of lawful relations.
David HumeDisbelief in futurity loosens in a great measure the ties of morality, and may be for that reason pernicious to the peace of civil society.
David HumeTo consider the matter aright, reason is nothing but a wonderful and unintelligible instinct in our souls, which carries us along a certain train of ideas, and endows them with particular qualities, according to their particular situations and relations. This instinct, 'tis true, arises from past observation and experience; but can anyone give the ultimate reason, why past experience and observation produces such an effect, any more than why nature alone should produce it?
David Hume
