Why is it said that the analogy of similar things is not inference but direct perception?

Why is it that analogy between things of the same kind is not inference but direct perception? For example, human beings certainly all share the same characteristics; any individual person certainly has something in common with humankind, and there is no need to compare this person with others of the same kind in order to determine that this person is indeed a human being and not of some other kind. A newborn infant, at birth, is known to be a human and not of another kind without any comparison; even in the mother's womb, one already knows that this child is a human and not of another kind. Such knowing is the knowing of direct perception, not the knowing of inference.

Products made from the same mold all have the same features; knowing the features of one product, one knows the features of the other products. This knowing is the knowing of direct perception, not the knowing of inference.

If one compares between things of the same kind and thereby knows the difference between the two, that is knowing through inference. For example, if one does not know whether a certain person is tall or short, one must compare that person with another person of standard height, or with the majority of people, before one can know—this is knowing through inference. But the result of this inferential knowing may be correct or may be incorrect; that is to say, the result may be direct perception, or it may be non-valid cognition.

One who knows a person's height through inference is not as intelligent as one who knows a person's height through direct perception. With direct perception, upon meeting someone, one can immediately judge based on experience and wisdom, without needing to compare and measure. Having to compare and measure shows a lack of the wisdom of direct perception—that one's powers of observation and judgment are not good enough, so one has no choice but to resort to inference. If the result judged through direct perception does not accord with the facts, then it is not direct perception but non-valid cognition, which shows that his wisdom is also not good enough; perhaps he is overly confident, and in that case he is not even as humble and cautious as the person who uses inference.
