Sagittarius is a fire sign and certain behavioral and psychological characteristics are thought to be dominant within this triplicity.
Taurus belongs to the quadruplicity of "fixed" signs and to the triplicity of the earth element.
Moreover, of the earth signs, Taurus' triplicity is of the fixed nature.
However, Scorpio's triplicity is also fixed like Taurus.
Scorpio's triplicity is found in the element of water.
We start, according to him, from a psychological triplicity in consciousness, consisting of sensation, personal will and impersonal reason, which by a priori laws of causality and substance carries us to the ontological triplicity of oneself as ego willing, the non-ego as cause of sensation, and God as the absolute cause beneath these relative causes.
So far this ontological triplicity is realism.
