Thinking in general is fed from two sources, firstly from subjective and in the last resort unconscious roots, and secondly from objective data transmitted through sense perceptions. Extraverted thinking is conditioned in a larger measure by these latter factors than by the former. Judgment always presupposes a criterion ; for the extraverted judgment, the valid and determining criterion is the standard taken from objective conditions,

whether in its further course it leads back again to objective data, external facts, and generally accepted ideas, or not.〔中略〕the practical thinking of the merchant, the engineer, or the natural science pioneer is concerned, the objective direction is at once manifest.

Thus it gives one the impression of a certain lack of freedom, of occasional short-sightedness, in spite of every kind of adroitness within the objectively circumscribed area.〔中略〕But essentially this thinking is no less fruitful and creative than introverted thinking, only its powers are in the service of other ends.

This type of man gives, the deciding voice not merely for himself alone but also on behalf of his entourage either to the actual objective reality or to its objectively orientated, intellectual formula. By this formula are good and evil measured, and beauty and ugliness determined.〔中略〕as the extraverted thinking type subordinates himself to his formula, so, for its own good, must his entourage also obey it, since the man who refuses to obey is wrong

If the formula is wide enough, this type may play a very useful role in social life, either as a reformer or a ventilator of public wrongs or a purifier of the public conscience, or as the propagator of important innovations. But the more rigid the formula, the more does he develop into a grumbler, a crafty reasqner, and a self-righteous critic, who would like to impress both himself and others into one schema.
