LOGIC (MS 339-1009)
This lecture begins the second half of the lecture series. The definition of "logic." Kinds of logical systems. All deductive reasoning is merely explicatory. Direct and indirect implication. What a word denotes and what it connotes. The sphere and the content of a word. Extension and comprehension. Being (all breadth, no depth) and Nothing (all depth, no breadth). Modification of the law of the inverse proportionality of extension and comprehension. The information of a term. On the subject of induction and hypothesis, CSP writes of the slight preponderance of true over false scientific inferences, and he finds that the reason for this is the vague tendency for the whole to be like any of its parts, taken at random.
