If the contemplation, even of inanimate beauty, is so delightful; if it ravishes the senses, even when the fair form is foreign tous: What must be the effects of moral beauty? And what influence must it have, when it embellishes our own mind, and is the result of our own reflection and industry?
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 HumeWe may well ask, What causes induce us to believe in the existence of body? but 'tis vain to ask. Whether there be body or not? That is a point which we must take for granted in all our reasonings.
David Hume..all arguments concerning existence are founded on the relation of cause and effect; that our knowledge of that relation is derived entirely from experience; and all our experimental conclusions proceed upon the supposition that the future will be conformable to the past. .... Without the influence of custom, we should be entirely ignorant of every matter of fact beyond what is immediately present to the memory and senses.
David HumeTis evident that all reasonings concerning matter of fact are founded on the relation of cause and effect, and that we can never infer the existence of one object from another, unless they be connected together, either mediately or immediately... Here is a billiard ball lying on the table, and another ball moving toward it with rapidity. They strike; and the ball which was formerly at rest now acquires a motion. This is as perfect an instance of the relation of cause and effect as any which we know, either by sensation or reflection.
David Hume
