an argument is a series of statements typically used to persuade someone of something or to present reasons for accepting a conclusion.
In logic, an argument requires a set of (at least) two declarative sentences (or “propositions“) known as the premisesalong with another declarative sentence (or “proposition”) known as the conclusion.
It is used to refer to some or all of the following: the primary bearers of truth-value, the objects of belief and other “propositional attitudes” (i.e., what is believed, doubted, etc.), the referents of that-clauses and the meanings of declarative sentences.
Propositions are the sharable objects of attitudes and the primary bearers of truth and falsity.
the Cambridge Dictionary of Philosophy defines ‘condition’ in an important sense not explained above: a condition is a state of affairs, “way things are” or situation—most commonly referred to by a nominalization of a sentence.
In philosophy, a state of affairs, also known as a situation, is a way the actual world must be in order to make some given proposition about the actual world true; in other words, a state of affairs (situation) is a truth-maker, whereas a proposition is a truth-bearer. Whereas states of affairs (situations) either obtain or fail-to-obtain, propositions are either true or false.
