4585. CONCERNING DISEASES. (All the infernals induce diseases, but with a difference according to the part to which they are attached, so that they may act from the opposite, to wit, in opposition to those in heaven, to whom the parts of the body correspond - for there are opposites to every society in heaven; for, as angels or angelic societies preserve in connection and soundness all things in man, so infernals, from the opposite [side], divide them. But it is only permitted them to inflow into the cupidities and falsities pertaining to man - not into man's organs. Only when man falls into disease, then they inflow also into those [organs] in man where the disease is; for nothing ever exists with man, save by a cause from the spiritual world. Man supposes that such things exist in him, and that there is nothing outside him that acts; when, yet, every natural has its cause from a spiritual, otherwise it would be without a cause; but, still, this does not interfere with the fact that they can be, and also ought to be, cured, or made sound, by natural means. The Lord's providence then concurs with such means: and thus, also, man is kept the longer away from faith concerning a providence in the minutest particulars; for, if he should believe this, and afterwards deny it, he would profane a sacred truth, which is itself a most dreadful hell.
