The Neoplatonic school of philosophy, whose origin is generally ascribed to
Ammonius Saccas and
Plotinus, accepted
Plato’s doctrines from a predominantly mystical point of view. The idealism of the Neoplatonists contributed to
Amos Bronson Alcott’s formulation of the doctrine of Genesis or Lapse—in which the universe is seen to be an emanation of God, with the divine
Nous as the source of all things, from human beings down to animals, plants, molecules, and finally atoms.
