" The body is the source of endless trouble to us by reason of the mere requirement of food; and is liable also to diseases which overtake and impede us in the search after true being: it fills us full of loves, and lusts, and fears, and fancies of all kinds, and endless foolery, and in fact, as men say, takes away from us all power of thinking at all. Whence come wars, and fightings and factions? Whence but from the body and the lusts of the body? Wars are occasioned by the love of money, and money has to be acquired for the sake and in the service of the body; and by reason of all these impediments we have no time to give to philosophy; and, last and worst of all, even if we are at leisure to betake ourselves to some speculation, the body is always breaking in upon us, causing turmoil and confusion in our inquiries, and so amazing us that we are prevented from seeing the truth. It has been proved to us by experience that if we would have true knowledge of anything we must be quit of the body—the soul in herself must behold things in themselves: and then we shall attain the wisdom which we desire, and of which we say we are lovers; not while we live, but after death: for if while in company with the body the soul cannot have pure knowledge, knowledge must be attained after death, if at all.
