BF299 Lecture 6: Abstraction
Document Summary
Arguing and reasoning is the transmission of truth from the premises o the conclusion inference warrant: deductive/inductive inference trajectory: up/down. Arguing up: thesis goes beyond strict evidence; the conclusion needs to be asserted with appropriate conditions and qualifications. Arguing down: thesis is exactly as reliable as the evidence, we must present the evidence with appropriate conditions and qualifications. Abstraction: the isolation of a feature of something independently of any instance that possesses that feature. Evidentiary: drawing an inference from concrete examples to an abstract claim, concrete examples serve as evidence for the abstraction, concrete claims (premises) support an abstract claim (a conclusion) Explanatory: an abstraction explains something about concrete examples, the truth of the abstract claim is taken for granted; its meaning is explained or illustrated by concrete instances.
