 Context examples: 

The ideal reasoner, he remarked, would, when he had once been shown a single fact in all its bearings, deduce from it not only all the chain of events which led up to it but also all the results which would follow from it.

(The Adventures of Sherlock Holmes, by Sir Arthur Conan Doyle)

It is one of those instances where the reasoner can produce an effect which seems remarkable to his neighbour, because the latter has missed the one little point which is the basis of the deduction.

(The Memoirs of Sherlock Holmes, by Sir Arthur Conan Doyle)

To carry the art, however, to its highest pitch, it is necessary that the reasoner should be able to utilise all the facts which have come to his knowledge; and this in itself implies, as you will readily see, a possession of all knowledge, which, even in these days of free education and encyclopædias, is a somewhat rare accomplishment.

(The Adventures of Sherlock Holmes, by Sir Arthur Conan Doyle)

You remember, he said, that some little time ago when I read you the passage in one of Poe’s sketches in which a close reasoner follows the unspoken thoughts of his companion, you were inclined to treat the matter as a mere tour-de-force of the author.

(The Memoirs of Sherlock Holmes, by Sir Arthur Conan Doyle)

Our visitor glanced with some apparent surprise at the languid, lounging figure of the man who had been no doubt depicted to him as the most incisive reasoner and most energetic agent in Europe.
