How can anything that exists from eternity have a cause, since that relation implies a priority in time and a beginning of existence?
Thirdly. It forms a strong presumption against all supernatural and miraculous relations, that they are observed chiefly to abound among ignorant and barbarous nations; or if a civilized people has ever given admission to any of them, that people will be found to have received them from ignorant and barbarous ancestors, who transmitted them with that inviolable sanction and authority, which always attend received opinions.
When we think back on our past sensations and feelings, our thought is a faithful mirror that copies its objects truly; but it does so in colours that are fainter and more washed-out than those in which our original perceptions were clothed.
That students of philosophy ought first to learn logics, then ethics, next physics, last of all the nature of the gods.”1.
By the term ‘impression’, then, I mean all our more lively perceptions when we hear or see or feel or love or hate or desire or will. These are to be distinguished from ideas, which are the fainter perceptions of which we are conscious when we reflect on our impressions.
However consistent the world may be, allowing certain suppositions and conjectures, with the idea of such a Deity, it can never afford us an inference concerning his existence.
All the materials of thinking are derived either from our outward senses or from our inward feelings: all that the mind and will do is to mix and combine these materials.
Empires may rise and fall; liberty and slavery succeed alternately; ignorance and knowledge give place to each other; but the cherry-tree will still remain in the woods of Greece, Spain, and Italy, and will never be affected by the revolutions of human society.
One that has well digested his knowledge both of books and men, has little enjoyment but in the company of a few select companions. He feels too sensibly, how much all the rest of mankind fall short of the notions which he has entertained. And, his affections being thus confined within a narrow circle, no wonder he carries them further than if they were more general and undistinguished.
Avarice, the spur of industry, is so obstinate a passion, and works its way through so many real dangers and difficulties, that it is not likely to be scared by an imaginary danger, which is so small, that it scarcely admits of calculation. Commerce, therefore, in my opinion, is apt to decay in absolute governments, not because it is there less secure, but because it is less honourable.
But though there be naturally a wide difference in point of delicacy between one person and another, nothing tends further to encrease and improve this talent, than practice in a particular art, and the frequent survey or contemplation of a particular species of beauty.
However, since we have never observed the construction of a world or observed the world constructors, we have no way of knowing what causal relations might be involved in such a project; all we can do is construct hypotheses, without any way of judging which of these are more or less likely.
They are consequently conjoined with each other in the conception; and the general idea of a line, notwithstanding all our abstractions and refinements, has in its appearance in the mind a precise degree of quantity and quality; however it may be made to represent others, which have different degrees of both.
The confusion, in which impressions are sometimes involved, proceeds only from their faintness and unsteadiness, not from any capacity in the mind to receive any impression, which in its real existence has no particular degree nor proportion. That is a contradiction in terms; and even implies the flattest of all contradictions, viz. that it is possible for the same thing both to be and not to be.
They all make up new species of crime and bring unhappiness in their train. When I hear a man is religious, I conclude he is a rascal, though I know some instances of very good men being religious .
It is only from the selfishness and confined generosity of men, along with the scanty provision nature has made for his wants, that justice derives its origin.
The beginning of motion in matter itself is as conceivable a priori as its communication from mind and intelligence.
Is he willing to prevent evil, but not able? then is he impotent. Is he able, but not willing? then is he malevolent. Is he both able and willing? whence then is evil?
It is well known, that, in all questions submitted to the understanding, prejudice is destructive of sound judgment, and perverts all operations of the intellectual faculties: it is no less contrary to good taste; nor has it less influence to corrupt our sentiment of beauty. It belongs to good sense to check its influence in both cases.
Whence can any cause be known but from its known effects? Whence can any hypothesis be proved but from the apparent phenomena? To establish one hypothesis upon another is building entirely in the air; and the utmost we ever attain by these conjectures and fictions is to ascertain the bare possibility of our opinion, but never can we, upon such terms, establish its reality.
