Hear the wise man:
The term “deduction” is most likely taken from the “Sherlock Holmes notes”, because it is fundamentally untrue and this method should rather be called “reduction” – that is, the conclusion of the primary fact by the consequences.
The term deduction was invented in antiquity and means "deduction of the private from the general". The opposite of deduction is induction. Assumption of general by particular manifestations. Reduction is the reduction of the complex to the simple. Despite the dust in the eyes of the girl, fine.
