Hume has some advice for the proffers of business or process improvement that fail to provide tangible evidence from the field that such advice actually works in a domain interesting to the reader ...
If we take our hand to any volume - of divinity, or school metaphysics, for instance - let us ask: "Does it contain any abstract reasoning concerning quantity of numbers?" No. "Does it contain any experimental reasoning concerning matter of fact and existence?" No. Commit it to the flames, for it can contain nothing but sophistry and illusion" And "The whole world presents nothing but the idea of a blind nature ... pouring forth from her lap, without discernment or parental care, her maimed and abortive children."
Show Me the Numbers!!
