Conviction is a nominalization and as such a distortion of reality according to NLP. Convictions are stronger than believes. Most of our convictions are trival like for instance the conviction that tomorrow the sun will still shine. Relevant convictions are way more uncommon than relevant believes. As there is a difference in meaning between conviction and belief it is important for the NLP practitioner to know whether a certain idea is a conviction or a belief because the submodalities of those two will differ. Confusing the two leads to working with the wrong set of submodalities.
As convictions limit people’s options the correct application of NLP entails breaking down negative convictions to the level of things you believe could happen (or they could not). It is wrong to use NLP to build strong positive convictions and certainty. This not only leads to less options for the person involved but it also leads to arrogance without competence as people use NLP to become convinced that they are able to do so whereas in fact they can’t.
Enemies of truth. – Convictions are more dangerous enemies of truth than lies.
Human, All Too Human part 1, paragraph 483
Conviction is the belief that on some particular point of knowledge one is in possession of the unqualified truth. This belief thus presupposes that unqualified truths exist; likewise that perfect methods of attaining to them have been discovered; finally, that everyone who possesses convictions avails himself of these perfect methods. All three assertions demonstrate at once that the man of convictions is not the man of scientific thought; he stands before us in the age of theoretical innocence and is a child, however grown up he may be in other respects. But whole millennia have lived in these childish presuppositions and it is from them that mankind’s mightiest sources of energy have flowed. Those countless numbers who have sacrificed themselves for their convictions thought they were doing so for unqualified truth. In this they were all wrong: probably a man has never yet sacrificed himself for truth; at least the dogmatic expression of his belief will have been unscientific or half-scientific. In reality one wanted to be in the right because one thought one had to be. To allow oneself to be deprived of one’s belief perhaps meant calling one’s eternal salvation into question. In a matter of such extreme importance as this the ‘will’ was only too audibly the prompter of the intellect. The presupposition of every believer of every kind was that he could not be refuted; if the counter-arguments proved very strong it was always left to him to defame reason itself and perhaps even to set up the ‘I believe because it is absurd’ as the banner of the extremest fanaticism. It is not conflict of opinions that has made history so violent but conflict of belief in opinions, that is to say conflict of convictions. But if all those who have thought so highly of their convictions, brought to them sacrifices of every kind, and have not spared honor, body or life in their service, had devoted only half their energy to investigating with what right they adhered to this or that conviction, by what path they had arrived at it, how peaceable a picture the history of mankind would present! How much more knowledge there would be! We should have been spared all the cruel scenes attending the persecution of heretics of every kind, and for two reasons: firstly because the inquisitors would have conducted their inquisition above all within themselves and emerged out of the presumptuousness of being the defenders of unqualified truth; then because the heretics themselves would, after they had investigated them, have ceased to accord any further credence to such ill-founded propositions as the propositions of all religious sectarians and ‘right believers’ are.
Human, All Too Human paragraph 630
To what extent even we are still pious. — It is said with good reason that convictions have no civic rights in the domain of science: it is only when a conviction voluntarily condescends to the modesty of an hypothesis, a preliminary standpoint for experiment, or a regulative fiction, that its access to the realm of knowledge, and a certain value therein, can be conceded, — always, however, with the restriction that it must remain under police supervision, under the police of our distrust. — Regarded more accurately, however, does not this imply that only when a conviction ceases to be a conviction can it obtain admission into science? Does not the discipline of the scientific spirit just commence when one no longer harbors any conviction ? . . . It is probably so: only, it remains to be asked whether, in order that this discipline may commence it is not necessary that there should already be a conviction, and in fact one so imperative and absolute, that it makes a sacrifice of all other convictions. One sees that science also rests on a belief: there is no science at all “without premises”. The question whether truth is necessary, must not merely be affirmed beforehand, but must be affirmed to such an extent that the principle, belief, or conviction finds expression, that “there is nothing more necessary than truth, and in comparison with it everything else has only secondary value” — This absolute will to truth: what is it? Is it the will not to allow ourselves to be deceived? Is it the will not to deceive? For the will to truth could also be interpreted in this fashion, provided one included under the generalization, “I will not deceive” the special case, ” I will not deceive myself” But why not deceive? Why not allow oneself to be deceived? — Let it be noted that the reasons for the former eventuality belong to a category quite different from those for the latter: one does not want to be deceived oneself, under the supposition that it is injurious, dangerous, or fatal to be deceived, — in this sense science would be a prolonged process of caution, foresight and utility; against which, however, one might reasonably make objections. What? Is not-wishing-to-be-deceived really less injurious, less dangerous, less fatal? What do you know of the character of existence in all its phases to be able to decide whether the greater advantage is on the side of absolute distrust, or of absolute trustfulness ? In case, however, of both being necessary, much trusting and much distrusting, whence then should science derive the absolute belief, the conviction on which it rests, that truth is more important than anything else, even than every other conviction? This conviction could not have arisen if truth and untruth had both continually proved themselves to be useful : as is the case. Thus — the belief in science, which now undeniably exists, cannot have had its origin in such a utilitarian calculation, but rather in spite of the fact of the inutility and dangerousness of the “Will to truth” of “truth at all costs” being continually demonstrated. “At all costs”: alas, we understand that sufficiently well, after having sacrificed and slaughtered one belief after another at this altar ! Consequently, “Will to truth” does not imply, ” I will not allow myself to be deceived,” but — there is no other alternative — ” I will not deceive, not even myself”: and thus we have reached the realm of morality. For let one just ask oneself fairly: “Why wilt thou not deceive?” especially if it should seem – and it does seem— as if life were laid out with a view to appearance, I mean, with a view to error, deceit, dissimulation, delusion, self-delusion; and when on the other hand it is a matter of fact that the great type of life has always manifested itself on the side of the most unscrupulous devious. Such an intention might perhaps, to express it mildly, be a piece of Quixotism, a little enthusiastic craziness; it might also, however, be something worse, namely, a destructive principle, hostile to life “Will to Truth, that might be a concealed Will to Death.- Thus the question Why is there science? leads back to the moral problem: What in general is the purpose of morality, if life, nature, and history are non-moral? There is no doubt that the conscientious man in the daring and extreme sense in which he is presupposed by the belief in science, affirms thereby a world other than that of life, nature, and history; and in so far as he affirms this “other world” what? must he not just thereby— deny its counterpart, this world, our world? … But what I have in view will now be understood, namely, that it is always a metaphysical belief on which our belief in science rests,— and that even we knowing ones of today, anti-metaphysical, still take our fire from the conflagration kindled by a belief a millennium old, the Christian belief, which was also the belief of Plato, that God is truth, that the truth is divine. But what if this itself always becomes more untrustworthy, what if nothing any longer proves itself divine, except it be error, blindness, and falsehood; — what if God himself turns out to be our most persistent lie? —
