Logic chopping fallacy (nit-picking, trivial objections) – Focusing on trivial details of an argument, rather than the main point of the argumentation. [95] [96] Ipse dixit (bare assertion fallacy) – a claim that is presented as true without support, as self-evidently true, or as dogmatically true. This fallacy relies on the implied ...
In model theory, the relation between a structure and a sentence where the structure makes the sentence true, according to the interpretation of the sentence's symbols in that structure. [261] satisfiability The property of a logical formula if there exists at least one interpretation under which the formula is true. schema
To express indefinite postponement, you might say that an event is deferred "to the [Greek] Calends" (see Latin). A less common expression used to point out someone's wishful thinking is Αν η γιαγιά μου είχε καρούλια, θα ήταν πατίνι ("If my grandmother had wheels she would be a skateboard").

In pointing this out to the false reasoner, one is not just pointing out a tactical psychological misjudgment by the questioner. It is not simply that the questioner falsely thought that the original point is placed under the guise of a semantic equivalent, or a logical equivalent, or a covering universal, or divided up into exhaustive parts ...
As Aristotle pointed out, since some sentences are questions, commands, or meaningless, not all can be truth-bearers. If in the proposal "What makes the sentence Snow is white true is the fact that snow is white" it is assumed that sentences like Snow is white are truth-bearers, then it would be more clearly stated as "What makes the meaningful-declarative-sentence Snow is white true is the ...
A statement is logically true if, and only if its opposite is logically false. The opposite statements must contradict one another. In this way all logical connectives can be expressed in terms of preserving logical truth. The logical form of a sentence is determined by its semantic or syntactic structure and by the placement of logical constants.
