IV. Body, Soul and Spirit

Through the sentient soul man is related to the animal. In animals, also, we observe the presence of sensations, impulses, instincts and passions. But the animal obeys these immediately. They do not, in its case, become interwoven with independent thoughts, transcending the immediate experiences.[^2] This is also the case to a certain extent with undeveloped human beings. The mere sentient soul is therefore different from the evolved higher member of the soul which brings thinking into its service. This soul that is served by thought will be termed the intellectual soul. One could also call it the mind-soul.
