Niiniluoto, Ilkka (2011). Abduction, tomography, and other inverse problems
Charles S. Peirce introduced in the late 19th century the notion of abduction as inference from effects to causes, or from observational data to explanatory theories. Abductive reasoning has become a...

Quote from "On Quantity, with special reference to Collectional and Mathematical Infinity"
…the distinguishing characteristic of mathematics is that it is the scientific study of hypotheses which it first frames and then traces to their consequences. Mathematics is either applied...

Quote from "On Quantity, with special reference to Collectional and Mathematical Infinity"
There is pure mathematics and applied mathematics. Pure mathematicians should strenuously object to a definition which should limit their hypotheses to such as are subservient to...
