Rousseau was mad but influential; Hume was sane but had no followers.
Can you pretend to show any such similarity between the fabric of a house and the generation of a universe? Have you ever seen Nature in any such situation as resembles the first arrangement of the elements? Have worlds ever been formed under your eye, and have you had leisure to observe the whole progress of the phenomenon, from the first appearance of order to its final consummation? If you have, then cite your experience and deliver your theory.
A man who hides himself, confesses as evidently the superiority of his enemy, as another who fairly delivers his arms.
There is a great difference between historical facts and speculative opinions ; nor is the knowledge of the one propagated in the same manner with that of the other.
It is well known, that every government must come to a period, and that death is unavoidable to the political as well as to the animal body.
Nature is always too strong for principle.
Secondly, we have several instances of habits, which may be revived by one single word; as when a person, who has by rote any periods of a discourse, or any number of verses, will be put in remembrance of the whole, which he is at a loss to recollect, by that single word or expression, with which they begin.
If only one can could know the essential natures of things, one might discover the ultimate reasons why they behave as they do: for the essential nature or essence of anything... if only it were truly adequate, all the behavioural properties of that thing must follow necessarily.
Thus if instead of saying, that in war the weaker have always recourse to negotiation, we should say, that they have always recourse to conquest, the custom, which we have acquired of attributing certain relations to ideas, still follows the words, and makes us immediately perceive the absurdity of that proposition; in the same manner as one particular idea may serve us in reasoning concerning other ideas, however different from it in several circumstances.
He insists that if we knew that God was all-good, we could account for the appearance of evil. However, we have to reason backward from our experience, which reflects a mixture of good and evil in the world. Philo contends that from what we experience, it is more likely that whatever being or force runs the world is morally neutral.
An ideal system, arranged of itself, without a precedent design, is not a whit more explicable than a material one which attains its order in a like manner; nor is there any more difficulty in the latter supposition than in the former.
A mind whose acts and sentiments and ideas are not distinct and successive, one that is wholly simple and totally immutable, is a mind which has no thought, no reason, no will, no sentiment, no love, no hatred; or, in a word, is no mind at all.
In all governments, there is a perpetual intestine struggle, open or secret, between authority and liberty; and neither of them can ever absolutely prevail in the contest.
The most perfect happiness, surely, must arise from the contemplation of the most perfect object.
In all societies people depend so much on one another that hardly any human action is entirely complete in itself, or is performed without some reference to the actions of others that are needed if the action is to produce what the agent intends.
The face of the earth is continually changing, by the encrease of small kingdoms into great empires, by the dissolution of great empires into smaller kingdoms, by the planting of colonies, by the migration of tribes. Is there any thing discoverable in all these events, but force and violence? Where is the mutual agreement or voluntary association so much talked of?
It is impossible for us to think of any thing, which we have not antecedently felt, either by our external or internal senses.
All beliefs about matters of fact or real existence are derived merely from something that is present to the memory or senses, and a customary association of that with some other thing.
In our reasonings concerning fact, there are all imaginable degrees of assurance. A wise man therefore proportions his belief to the evidence.
It is as easy for the imagination to form monsters and to join incongruous shapes and appearances as it is to conceive the most natural and familiar objects.
When I enter most intimately into what I call myself, I always stumble on some particular perception or other, of heat or cold, light or shade, love or hatred, pain or pleasure. I never can catch myself at any time without a perception, and never can observe any thing but the perception. When my perceptions are removed for any time, as by sound sleep; so long am I insensible of myself, and may truly be said not to exist.
