15. Deduction vs. Induction & The Saltatorial Theory
Deduction （reasoning from the general to the particular 演绎法）
‘Here is a gentleman of a medical type, but with the air of a military man. Clearly an army doctor, then. He has just come from the tropics, for his face is dark, and that is not the natural tint of his skin, for his wrists are fair. He has undergone hardship and sickness, as his haggard face says clearly. His left arm has been injured. He holds it in a stiff and unnatural manner. Where in the tropics could an English army doctor have seen much hardship and got his arm wounded? Clearly in Afghanistan.’
A Study in Scarlet, Chapter 2 The Science of Deduction

16. Deduction vs. Induction & The Saltatorial Theory
“… I do not fear to match my cunning and powers of induction against his."
Induction（reasoning from detailed facts to general principles 归纳法）
The Saltatorial Theory
“My process is more modern. I call it the saltatorial theory. Without bothering with the tedious mental phenomena necessary to the solution of a mystery from slight clues, I jump at once to a conclusion. ”
*Both are the antithesis of Holmesian deduction.
