'Facts, Watson, Facts!'
The Science of Deduction
In philosophy, empiricism is a theory of knowledge that is practical rather than abstract, and asserts that knowledge arises from experience rather than revelation.
Empiricism is one view held about how we know things, and so is part of the branch of philosophy called epistemology, which means "theory of knowledge". Empiricism emphasizes the role of experience and evidence, especially sensory perception, in the formation of ideas, while discounting the notion of innate ideas.
In the philosophy of science, empiricism emphasizes those aspects of scientific knowledge that are closely related to evidence, especially as discovered in experiments.
It is a fundamental part of the scientific method that all hypotheses and theories must be tested against observations of the natural world, rather than resting solely on a priori reasoning, intuition, or revelation.
Hence, science is considered to be methodologically empirical in nature.
The term "empiricism" has a dual etymology.
It comes from the Greek word εμπειρισμός, the Latin translation of which is experientia, from which we derive the word experience. It also derives from a more specific classical Greek and Roman usage of empiric, referring to a physician whose skill derives from practical experience as opposed to instruction in theory.
His actual methods relied on pure reasoning and not any flouncy assumption or emotional response.
This is not to say he was an emotional dullard. He could be as as charming any anyone else in public - but this was usually a means to an end.
He didn't suffer fools for long - but he sympathised with the downtrodden or those who had been the victims of rough justice.
Holmes and Watson were not homosexual (Watson was married at least once) and Holmes at best could have been described as a pseudo-misogynist.
He was actually ironically something of a subverted 'ladies' ' man'. Women turned to him for strength and support in their times of crises. Look at his female client list.
And to him, there was only ever one woman - Irene Adler who outwits him in A Scandal in Bohemia.
