This type of man elevates objective reality, or an objectively oriented intellectual formula, into the ruling principle not only for himself but for his whole environment. By this formula good and evil are measured, and beauty and ugliness determined. Everything that agrees with this formula is right, everything that contradicts it is wrong…. Because this formula seems to embody the entire meaning of life, it is made into a universal law which must be put into effect everywhere all the time, both individually and collectively. Just as the extroverted thinking type subordinates himself to his formula, so, for their own good, everybody round him must obey it too, for whoever refuses to obey it is wrong—he is resisting the universal law, and is therefore unreasonable, immoral, and without a conscience. His moral code forbids him to tolerate exceptions; his ideal must under all circumstances be realized…. This is not from any great love of his neighbor, but from the higher standpoint of justice and truth… “oughts” and “uses” bulk large in this program. If the formula is broad enough, this type may play a very useful role in social life as a reformer or public prosecutor or purifier of conscience…. But the more rigid the formula, the more he develops into a martinet, a quibbler, and a prig, who would like to force himself and others into one mould. Here we have the two extremes between which the majority of these types move. ~ C.G. Jung, Psychological Types, 347
