The middle of three soul-members in Steiner's anthropology, the part of inner life that lifts feeling and sensation into thinking.
The Intellectual Soul (German Verstandes-Gemütsseele) is, in Rudolf Steiner's Theosophy, the second of three soul-members standing between the sentient soul below and the consciousness soul above. It is the part of inner life where pure sensation becomes thinking, where feeling becomes judgment, and where the I first finds a stable centre from which to articulate the world. Steiner sometimes calls it the rational soul or mind-soul.
In Steiner's Own Words
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. 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. The intellectual soul permeates the sentient soul.
What it Means Today
Steiner's threefold soul (sentient, intellectual, consciousness) is the structural backbone of his psychology, and the intellectual soul is its middle hinge. Where the sentient soul still belongs partly to the body and reacts to the world the way an animal does, and where the consciousness soul reaches up toward self-knowing spirit, the intellectual soul is where sensation first cools into thought and where feeling first organises itself into reason. Steiner places its historical flowering in the Greco-Roman cultural epoch, the period when philosophy, civic law, and reasoned discourse became cultural achievements rather than priestly secrets. That is why he uses the doubled German Verstandes-Gemütsseele, intellect-and-feeling-soul: the faculty is not cold logic but warmed cognition, thinking saturated with inwardness.
For a contemporary practitioner this is the layer of soul-life that depth psychology has spent a century mapping under different names. What Steiner calls the intellectual soul corresponds closely to what Jung described as the ego-functions of thinking and feeling working together, and what cognitive science studies as the appraisal layer between raw affect and self-reflective awareness. To work with the intellectual soul concretely is to notice the moment when a sensation in the body becomes a judgment in words, then to ask whether the judgment is true to the feeling or has run ahead of it. Steiner's claim is that this middle soul has its own laws, and that learning them is what makes thinking trustworthy. The intellectual soul works in mental pictures, the individualized concepts the soul forms and keeps. The intellectual soul of the Greek age mirrors itself in Zeus and the Greek soul.
