The tree of life too may be understood as that more divine thought that has its origin in the world of sense, and the ascent through that to the originating and constructive cause of all. And this was the name He gave to every tree, implying fulness and indivisibility, and conveying only participation in what is good. But by the tree of the knowledge of good and evil, we are to understand that sensible and pleasurable food which, sweet though it seems, in reality brings him who partakes of it into communion with evil. For God says, Of every tree in Paradise thou mayest freely eat Gen. ii. 16.. It is, me-thinks, as if God said, Through all My creations thou art to ascend to Me thy creator, and of all the fruits thou mayest pluck one, that is, Myself who art the true life: let every thing bear for thee the fruit of life, and let participation in Me be the support of your own being. For in this way thou wilt be immortal. But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die Ibid. 17.. For sensible food is by nature for the replenishing of that which gradually wastes away and it passes into the drought and perisheth: and he cannot remain incorruptible who partakes of sensible food.
