Suggestion occupies a contested and generative position within the depth-psychology corpus, functioning simultaneously as a clinical tool, a theoretical problem, and a criterion for pathological susceptibility. Pierre Janet establishes the foundational clinical definition: suggestion is the complete, autonomous development of an idea's elements without participation of will or personal consciousness — a phenomenon Janet insists is diagnostically specific to hysteria and constitutive of its central stigma, suggestibility. For Janet, suggestibility is not merely heightened compliance but evidence of a dissociated personality structure incapable of assimilating external influence through the integrating action of the self. Freud's engagement with the term is dialectical: having abandoned hypnotic suggestion as a method, he concedes that psychoanalysis rediscovers suggestion in the form of transference, a recognition he uses to sharpen rather than collapse the distinction between the two modes of therapeutic action. Jung carries the critique furthest, condemning suggestion as a form of magic operating in the dark, incompatible with analytical ethics, and inimical to the development of the patient's autonomous personality. Yet Jung simultaneously acknowledges the inescapability of unconscious suggestion in clinical work. Across these registers the term marks a fault-line between influence and individuation, between therapeutic efficacy and the patient's ethical maturation.
In suggestion you meet with nothing of the kind. There is no effort on the part of the subject, no addition of strength from his anterior tendencies, no work of his personality.
Janet defines suggestion's distinctive mechanism as the development of an idea entirely without voluntary effort, personal will, or the integrating force of the subject's prior character.

Suggestion is a precise and relatively rare phenomenon; it presents itself experimentally or accidentally only with hystericals, and, inversely, all hystericals, when we study them from this standpoint, present this same phenomenon in a higher or lower degree.
Janet argues that genuine suggestibility is diagnostically exclusive to hysteria, making it the most important psychological stigma of that condition.

Methods of treatment based on suggestion are deceptive makeshifts; they are incompatible with the principles of analytical therapy and should be avoided if at all possible.
Jung condemns suggestion-based treatment as ethically deficient and fundamentally opposed to analytical aims, while acknowledging that unconscious suggestion can never be entirely eliminated.

"A phenomenon is hysterical," said Babinski, "when it can be produced through suggestion and cured through persuasion." ... hysteria is defined by suggestion.
Janet surveys the tradition — from Charcot to Babinski — in which suggestion serves as the defining criterion of hysterical phenomena, crystallizing the nosological weight the term had acquired.

we have only abandoned hypnosis in our methods in order to discover suggestion again in the shape of transference.
Freud acknowledges that psychoanalysis does not escape suggestion but transforms it, relocating its mechanism from direct hypnotic command to the libidinal dynamics of transference.

his chances of convincing the patient or of achieving any therapeutic results depend chiefly upon suggestion. Let no one deceive himself about this. In itself, suggestion is not to be despised, but it has serious limitations.
Jung concedes suggestion's pragmatic utility while warning that reliance on it undermines the patient's independence of character and forecloses genuine analytical work.

This complete automatic development of the personality, in the fashion of a parasite, is not met with in the normal mind.
Janet distinguishes true suggestibility — an autonomous, parasite-like idea-development — from ordinary docility and belief, restricting pathological suggestion to minds unable to integrate experience through conscious personality.

The mental stigma of suggestibility — The distinct meaning of the word 'suggestion' — Description of the principal facts of suggestion — The complete development of the elements contained in an idea, without any participation of the will or of the personal consciousness
Janet's chapter overview establishes the conceptual architecture within which suggestion is analyzed as hysteria's central psychological stigma, insisting on a precise, restricted definition.

experience shows that in abandoning direct suggestion we have given up nothing irreplaceable... The exercise of the hypnotic method makes as little demand for effort on the part of the patient as it does on the physician.
Freud argues that the economy of effort in direct suggestion is precisely its deficiency, a minimal exertion incapable of shifting the substantial energic burden of neurosis.

it may not be superfluous, at this point, to say a few words about the frequently heard objection that the constructive method is simply 'suggestion.'
Jung (via Chodorow) defends the constructive-symbolic method against the charge that it reduces to suggestion, distinguishing purposive symbol-evaluation from the reductive imposition of meaning.

is suggestion in the waking state equivalent to suggestion in the hypnoid state, as Bernheim now asserts, after having used suggestion for many years in hypnosis?
Jung rehearses Bernheim's late-career collapse of the distinction between waking and hypnotic suggestion, framing the question of state-dependency as central to evaluating psychocatharsis versus suggestion therapy.

I am convinced, for my part, that hysterical contracture has its own laws, quite peculiar to it... All this is outside of the thought of the subject.
Janet argues that hysterical symptoms follow autonomous physiological laws beyond any ideational suggestion, complicating purely representationalist accounts of hysteria.
