“Between stimulus and response, there is a space. In that space is our power to choose our response. In our response lies our growth and our freedom.” — Viktor E. Frankl
By the mid-twentieth century, the dominant models of human psychology were deeply deterministic. Freudian psychology posited that the unconscious — shaped by early childhood experience, repressed drives, and instinctual forces — governed behavior in ways that the conscious self could only partially and imperfectly control. Behaviorism, dominant in American academic psychology, reduced human behavior entirely to the output of conditioned stimulus-response chains. Sociobiology was beginning to argue that genes shaped disposition in ways that left little room for genuine freedom.
Against all of these, Frankl mounts a vigorous and experientially grounded defense of human freedom.
He calls the reductive view pan-determinism — the belief that human beings are entirely determined by prior causes: biological, psychological, or social. Pan-determinism denies that there is a meaningfully free dimension of human existence — a space in which the person genuinely chooses rather than merely executing the product of prior forces.
Frankl’s argument against pan-determinism is not primarily philosophical. It is empirical. In the camps, he watched human beings under conditions designed to reduce them to pure survival machines — conditions that, if pan-determinism were true, should have produced uniform behavior. They did not.
Under identical conditions — the same deprivation, the same violence, the same proximity to death — prisoners made strikingly different choices. Some shared their last bread with others. Some informed on fellow prisoners to gain an extra ration. Some maintained a dignity that the guards found unsettling. Some collapsed into a brutality that matched or exceeded that of their captors.
These differences were not fully explained by prior conditioning, by personality type, or by the circumstances of their backgrounds. They pointed, Frankl concluded, to something irreducible — a dimension of freedom that persisted even in the most extreme conditions, the dimension he called the specifically human.
The formulation often attributed to Frankl — “between stimulus and response, there is a space” — captures the core of his case for human freedom. The stimulus is whatever happens to the person: the circumstances they are in, the treatment they receive, the bodily states they experience. The response is what the person does or how they bear what happens.
Pan-determinism says the stimulus determines the response. Frankl says there is a gap — a moment of freedom — between the two. That gap may be very small. In extreme conditions it may feel absent. But it is never entirely gone, and exercising it — learning to recognize and inhabit it — is the practice of distinctly human living.
Frankl describes this freedom in terms of what he calls self-distancing and self-transcendence. Self-distancing is the capacity to step back from one’s own immediate impulses, reactions, and conditioning — to observe them rather than simply executing them. Humor is one expression of this: to laugh at oneself is to demonstrate that one is not entirely identical to one’s situation.
Self-transcendence is the complementary movement — the capacity to move toward something or someone beyond oneself. Where self-distancing creates the space of freedom, self-transcendence fills it with content: this is what the freedom is for, this is what I am turning toward.
Together, these two movements constitute what Frankl means by the specifically human. An animal cannot distance itself from its instincts or transcend its immediate drives. A human being can — and this capacity is the foundation of human dignity.
Frankl is adamant on one point: suffering that can be relieved or avoided should be relieved and avoided. It would be masochistic, he says, to claim that suffering is inherently valuable. Unnecessary suffering is simply bad.
But not all suffering can be avoided. Illness, loss, the deaths of those we love, the limitations of our own natures, the fundamental contingency of existence — these cannot be eliminated. The question then is not whether to suffer but how.
When suffering cannot be avoided, it becomes the occasion for the third category of meaning that Frankl identifies: attitudinal values. One cannot choose to not be ill, to not have lost someone, to not be facing death. But one can choose — within the space between stimulus and response — the attitude with which one faces these things.
Frankl describes patients dying of terminal illness who were transformed by the recognition that how they died — with dignity, with love, with the courage to say what needed to be said — was within their control and mattered deeply. He describes people for whom the discovery that unavoidable suffering could be borne meaningfully gave the last weeks of their lives an intensity and beauty that they had not known before.
This is not consolation philosophy. It does not say that suffering is good. It says that when suffering is genuinely unavoidable, the manner in which it is borne is the last and often the most important freedom available to the person bearing it.
Frankl is sometimes read as implying that all suffering can be redeemed by the right attitude — that there is always a meaning to be found if one looks hard enough. He does not mean this. He is not addressing the theological question of why suffering exists or whether it is part of some larger design. He is making a clinical and phenomenological claim: that patients who were able to find some form of meaning in their unavoidable suffering — even if only the meaning of bearing it with dignity — fared better psychologically than those who could not.
This is an empirical observation, not a metaphysical guarantee. It does not promise that all suffering has meaning. It observes that the search for meaning in suffering can itself be a source of psychological strength.
Frankl distinguishes his concept of mental health from models centered on self-actualization (most prominently associated with Abraham Maslow). Self-actualization describes a process of becoming the fullest version of oneself — developing one’s capacities, realizing one’s potential.
Frankl does not object to this as a description of one aspect of psychological development. But he argues that it is incomplete and can be misleading. Self-actualization as a goal — something one aims at for its own sake — tends to produce exactly the opposite of what it promises.
He uses the analogy of a boomerang. A boomerang returns to the thrower only when it misses its target. Self-actualization works similarly: it tends to come as a byproduct of genuine engagement with something beyond oneself. When a person is wholly absorbed in a work they find meaningful, in the loving care of another person, in the service of a cause they believe in — self-actualization occurs naturally, as an effect of self-transcendence.
When a person makes self-actualization their direct goal — when they ask “how can I become the best version of myself?” rather than “what does this situation call me to do?” — they typically become self-preoccupied in a way that is antithetical to genuine meaning and, paradoxically, to genuine self-actualization.
The implication for therapy, and for life more broadly, is that the route to psychological wholeness runs through engagement with what is genuinely worth engaging — through love, meaningful work, and honest confrontation with unavoidable suffering — not through any direct program of self-improvement.
