Note 664 — CANTO XXV.

The forms, etc.: The word form is here to be taken in its scholastic sense of virtus formativa, the inherited power of modifying matter into an organised body. ‘This, united to the divinely implanted spark of reason,’ says Philalethes, ‘constitutes, on Dante’s system, a human soul. Even after death this power continues to be an essential constituent of the soul, and constructs out of the elements what seems to be a body. Here the sinners exchange the matter they have thus made their own, each retaining, however, his proper plastic energy as part of his soul.’ Dante in his Convito (iii. 2) says that ‘the human soul is the noblest form of all that are made under the heavens, receiving more of the Divine nature than any other.’
