And that this joyfulness and reverence are a necessary part of theoretic pleasure is very evident when we consider that, by the presence of these feelings, even the lower and more sensual pleasures may be rendered theoretic. Thus Aristotle has subtly noted, that "we call not men intemperate so much with respect to the scents of roses or herb-perfumes as of ointments and of condiments," (though the reason that he gives for this be futile enough.) For the fact is, that of scents artificially prepared the extreme desire is intemperance, but of natural and God-given scents, which take their part in the harmony and pleasantness of creation, there can hardly be intemperance; not that there is any absolute difference between the two kinds, but that these are likely to be received with gratitude and joyfulness rather than those, so that we despise the seeking of essences and unguents, but not the sowing of violets along our garden banks. But all things may be elevated by affection, as the spikenard of Mary, and in the Song of Solomon, the myrrh upon the handles of the lock, and that of Isaac concerning his son. And the general law for all these pleasures is, that when sought in the abstract and ardently, they are foul things, but when received with thankfulness and with reference to God's glory, they become theoretic; and so I can find something divine in the sweetness of wild fruits, as well as in the pleasantness of the pure air, and the tenderness of its natural perfumes that come and go as they list.
