"It is for living things that air has such a dynamic mobility."

  -"Philosophia Perennis: Volume 1: An Introduction to Philosophy as Wisdom" by Francis Maluf

“Not only men have souls, but even trees have souls. Anything alive must have a cause, a principle of its vital activities. An angel* is not a soul. An angel is indeed something living. It is living and existing, but by a life not dependent on matter. An angel is an immaterial living being. Birds, fishes, and trees have souls, but these souls are not spirits. The angels are spirits, but they are not souls. In man those two realities meet. In man there is a soul but that soul is spiritual. That is one of the great truths that psychology teaches, and here we mean true psychology, that which is part of philosophia perennis, and part of eternal wisdom.”
