Concepts of Evidence

From Carnap, Logical Foundations of Probability, p. 163. See Also Rabinovitch, p. 109

1. Classificatory
• e renders h probable
2. Comparative
• e1 renders h1 more probable than e2 renders h2
• (e1 & e2) render h more probable than e1 alone does.
• e1 renders h1 more probable than it does h2
3. Quantitative
• the probability of h on e is r
