Theophilus. As to your first matter, concerning magical eyes; I should have thought the thing plain enough already. But you may understand it thus. When a carpenter cuts timber into various shapes and forms, and then joins one piece to another, till it is formed into the shape of a house; this is no magical work, because one part does not grow from the other, till the whole is brought forth, and therefore there is no need of magical eyes to see what this work is. But when an oak groweth from an acorn, or a plant from a seed in the ground, here the work is magical; that is, it is a birth or product generated from the working will in the acorn and seed, from whence the stem, and all its branches and fruits, grow forth; which working will continueth till the plant or tree hath reached its limit, that is, till the working will in the seed hath spent itself. Now all this is a magical work, and therefore can only be seen by such magical eyes as can see into the beginning, and go on with the working of that which works and generates in the tree or plant.
