This assertion (hereafter, the PopperвЂ“Reichenbach thesis), which rallied hypothetico-deductivists and probabilistic inductivists in spite of otherwise opposed views on scientific methodology, resulted in a long-lasting consensus that there can be no вЂlogicвЂ™ of discovery.Д¬onsequently, HolmesвЂ™ вЂњScience of Deduction and AnalysisвЂќ reflects epistemological and methodological insights suppressed by the PopperвЂ“Reichenbach thesis. Footnote 1 JevonsвЂ™ ideas predate by 50В years the discussion of scientific discovery from the 1930s, that came to an abrupt end when Popper ( 1992) and Reichenbach ( 1938) asserted the impossibility of a rational reconstruction of discovery processes. On occasion, Conan Doyle lets Holmes depict this picture, explaining the principles of logic and probability that support his conclusions, and echoing in the fiction the real-world epistemological views of early proponents of George BooleвЂ™s вЂnew logicвЂ™, in particular, Stanley William Jevons (1835вЂ“1882). Not only did Conan Doyle model HolmesвЂ™ abilities (and attitude) on BellвЂ™s, he also formed his own picture of the вЂњScience of Deduction and AnalysisвЂќ (as per the title of the second chapter of A Study in Scarlet) that underlies them. Quite easy, gentlemen, if you will only observe and put two and two together.вЂ™ (Liebow 1982,В p.В 135) Then I knew he had to ring the bells to-morrow. Did you not notice the callosities on them caused by the ropes? Also, this is Saturday, and when I asked him if he could not come back on Monday, he said he must be getting home tonight. What! You didnвЂ™t make that out! Did you not notice the Northumbrian burr in his speech, too soft for the south of Northumberland? One only finds it near the Tweed. вЂAh,вЂ™ said Bell, when the outpatient had left bewildered, вЂyou all know about that as well as I did. вЂI am all that,вЂ™ said the man, вЂbut how do you know? I never told you.вЂ™ Well do I remember the gasping astonishment of an outpatient to whom suddenly remarked, вЂOf course I know you are a beadle and ring the bells on Sundays at a Church in Northumberland somewhere near the Tweed.вЂ™ LiebowвЂ™s Joe Bell, Model of Sherlock Holmes (1982), would inspire HolmesвЂ™ claims that one can deduce вЂњa manвЂ™s callingвЂќ from ( inter alia) the calluses on his hands:

Ten years later, an episode of BellвЂ™s life, recounted by one Doctor Charles Watson McGillivray and reported in E.

Bell encouraged his students to draw inferences from observations of their patients and was keen on schooling them on how to do so. In 1877, doctor-in-training Arthur Conan Doyle served as an assistant to Scottish surgeon Joseph Bell (1837вЂ“1911) at the Royal Edinburgh Infirmary. ( A Study in Scarlet, I, 2)Дismissing HolmesвЂ™ claims as fiction may be tempting but would be a mistake for he describes real-world skills. That all united should fail to enlighten the competent inquirer in any case is almost inconceivable. By a manвЂ™s finger-nails, by his coat-sleeve, by his boot, by his trouser-knees, by the callosities of his forefinger and thumb, by his expression, by his shirt-cuffs-by each of these things a manвЂ™s calling is plainly revealed. Rom a drop of water a logician could infer the possibility of an Atlantic or a Niagara without having seen or heard of one or the other.
