'With respect to plants as animals, we are wrong in speaking as if the object of life were only the bequeathing of itself. The flower is the end and proper object of the seeds, not the seed of the flower. The reason for the seed is that flowers may be, not the reason of flowers that seeds may be. The flower itself is the creature which the spirit makes; only, in connection with its perfectedness, is placed the giving birth to its successor.' (II, 60.)
