Psychic Self-Defence (Dion Fortune) · 9 of 129

Preface-i

So much occult knowledge is abroad in the world, so much of the kind of things described in these pages is going on unknown and unsuspected in our midst, that it is very desirable that men of goodwill should investigate the forces which men of evil will have perverted to their own ends. These things are the pathologies of the mystic life, and if they were better understood, many tragedies might be averted. On the other hand, it is not well that everybody should indulge in the study of textbooks of pathology. A vivid imagination and a weak head are a disastrous combination. The readers of that one-time “best seller,” Three Men in a Boat, may remember the fate of the individual who spent a wet Sunday afternoon reading a medical textbook. At the finish he was firmly convinced he had got every single disease described therein with the single exception of house maid’s knee. This book is not intended merely to make the flesh creep, but is designed as a serious contribution to a little-understood aspect of abnormal psychology, perverted, in some instances, to the purposes of crime. It is a book intended for serious students and for those who find themselves confronted by the problems it describes, and who are trying to understand them and find a way out. My chief aim in speaking so frankly is to open the eyes of men and women to the nature of the forces that are at work below the surface of everyday life. It may happen to any one of us to break through the thin crust of normality and find ourselves face to face with these forces. Reading of the cases cited in this book, we may well say that there, but for the grace of God, goes any one of us. If I can give in these pages the knowledge which protects, I shall have fulfilled my purpose.

Themes
Evil As Privationtheology

Augustinian and Plotinian doctrine that evil has no positive being of its own but is a lack, distortion, or absence of the good — denying ontological dualism while preserving moral seriousness.

The description of forces being 'perverted' suggests a corruption or distortion of something that should be otherwise, aligning with the idea of evil as a perversion rather than a primary substance.

Magical Willpraxis

The doctrine that human volition, cultivated by discipline and emancipated from passion and servitude, is the primary instrument of magical operation — will confirmed by persistent acts acquires causal power over self, others, and nature; distinct from faith and from mere desire.

The text references 'men of evil will' perverting forces, acknowledging the causal power of human volition in the occult realm.

All passages →
Psychic Attackpraxis

The doctrine and practice of one person deliberately inflicting harm on another through trained will, mind-power, or occult technique alone, without physical contact — producing exhaustion, illness, breakdown, or death in the victim; recognised cross-culturally as witchcraft, hexing, or the evil eye, and treated in Western esotericism as a genuine occult hazard requiring diagnosis and defence rather than dismissed as superstition. Distinct from magical_will (the general doctrine that trained volition has causal power, of which this is one malevolent application) and from spirit_conjuration (which subordinates an already-existing summoned spirit, rather than directing the operator's own power at a person).

The central theme is 'Psychic Self-Defence,' explicitly addressing forces perverted by men of evil will to harm others, which defines the concept of deliberate psychic assault.
