AE 739b - the knowledges of good and evil

AE 739b [8,10]
The knowledges of good and evil from the Lord from which is wisdom,
and the knowledges of good and evil from the world from which is science,
were represented by "the tree of lives"
and by "the tree of the knowledge of good and evil"
in the midst of the garden.
That they were permitted to appropriate to themselves
knowledges from every source,
not only from heaven but also from the world,
provided they did not proceed in the inverted order,
by reasoning about heavenly things from worldly knowledges,
instead of thinking about worldly things from heavenly things . . .

. . . the sensual person believes that he knows all things,
and that nothing is concealed from him;
but not so the celestial person,
who knows that he knows nothing from himself but only from the Lord,
and that what he does know is so little
as to be scarcely anything as compared with what he does not know.
