DICTIOANARY OF SYMBOLS
In his On Psychic Energy, Jung has asserted that: ‘The spiritual appears in the psyche as an instinct, indeed as a real passion. . . It is not derived from any other instinct, but is a principle sui generis, that is, a specific and necessary form of instinctual power.’ Apart from the fact that this asseveration would seem to put an end to the assumption that science is necessarily materialistic, its importance lies in that it takes up the essential platonic doctrine of the soul, which we here equate with the Jungian principle of spirituality, even though at times it may be necessary to treat the two principles separately. Plato in Timaeus, Plotinus in the Enneads, elaborate the idea that the soul is a stranger on earth, that it has de- scended from the spaceless and timeless universe, or that it has ‘fallen’ on account of sin into matter, that it initiates a process of life-giving growth corresponding to the period of involution.
