13 ;;Quote: empiricism--a sentence is either true or false if it is analytic (logical meaning) or tested by experiential evidence

14 ;;Quote: condition of adequacy--if a sentence does not have a truth value than so with everything that contains it nonvacuously

14 ;;Quote: empirical significance if relate a hypothesis to observation sentences that can be ascertained by direct observation

15 ;;Quote: problem of unbounded domains--a universally quantified sentence can not be empirically confirmed; so without a truth value

17 ;;Quote: requirement of definability--any term with empirical significance must be definable by observation terms; used to form significant sentences

17 ;;Quote: if insist on empirically defined terms, how can one handle disposition terms such as 'fragile'?

18 ;;Quote: could define empirically significant terms via reduction sentences, but couldn't handle concepts such as length (could be irrational)

19 ;;Quote: a statement in isolation has no experiential implications; need other hypothesis, e.g., from science; experiential meaning is elliptical

20 ;;Quote: only entire theoretical systems formulated in a language with a well-determine structure have cognitive significance

20+;;Quote: a cognitively significant, theoretical system is interpreted in terms of observables without isolated sentences

22 ;;Quote: in science we must rise above the level of direct observation; need theoretical constructs to formulate high-level laws and hypotheses

22+;;Quote: strict avoidance of isolated sentences would disallow hypothesis formation and new conceptualizations

22 ;;Quote: compare theories on their clarity, predictive power, simplicity, and confirmations

22+;;Quote: how can one distinguish between science and speculation? Is there a logical evaluation of a theory?

Higg. ;;Note: any logical definition of empirical significance appears to run into trouble; gives example
