etc.

(5) Touch.

(6) Mind.
The combination of all these and reflection on their significance.
These unusual impressions (1-5) produce unusual brain-changes; hence
their summary (6) is of unusual kind. Its projection back into the
apparently phenomenal world is therefore unusual.
Herein then consists the reality of the operations and effects of
ceremonial magic,[6] and I conceive that the apology is ample, as far as
the “effects” refer only to those phenomena which appear to the magician
himself, the appearance of the spirit, his conversation, possible shocks
from imprudence, and so on, even to ecstasy on the one hand, and death
or madness on the other.
But can any of the effects described in this our book Goetia be
obtained, and if so, can you give a rational explanation of the
circumstances? Say you so?
