Logic/Proposition/Statement/MatesVsPropositions/Logic/Mates: the structure of a proposition should not be confused with that of the corresponding assertion - e.g. "Kennedy won the election" - "he won the election" (various Propos possible.). Also their structure is not easy to see from the accompanying statement - also MatesVsThoughts: different structure - all not to be divided in categories like singular subjunctive, affirming, hypothetically, etc. - also VsJudgment: rather "act of the mind", not in logic - instead: only statements - solution: equivalence: the statement is true iff. the claim that is set up with it, is true - corresponding for judgments, thoughts, etc. - Index words / solution: complete with place and time.
