5. Of the Spirits
D. Leaving the Humors, let us proceed to the Spirits. Why are they called Impulsive by Hippocrates?
C. Because that by their means the Corporeal Bulks of Living Creatures are moved, perceive, live and subsist; even by their aid the dull and heavy bodies of living creatures are subjected to the Empire of the Soul, and brought under its government and power. Moreover, by means of them, the corporeal substance coheres with the incorporeal; whereby it comes to pass, that they are as it were the Bands that tie both Soul and Body together.

D. What is the Vital Spirit?
C. That which is bred in the left part of the Heart, of the Natural Spirit, and the Air sucked in by the Lungs, whence it is conveyed through the Arteries to every part, to cherish the inbred Spirit, corroborate the Natural Heat, and restore Strength.

'Spirit', from Spiritus, means 'Breath', or 'Spirit', but classically also a highly refined substance giving Vital Energy. It therefore overlaps concepts of Spirit and Qi, or Vital Force.
This clearly talks of the Pre-Natal or Inherited Qi of TCM
And this relates to Post-natal or Acquired Qi.
The Animal Spirit gives consciousness, and is called so as it is only found in Animals.
The Vital Spirit is formed from Natural Spirit ('Food Qi') mixed with Air, in other words, Qi. It noursihes Natural Heat (Yang) and gives strength.
The Natural Spirit is the best essence of Food, generated in the Liver.
