Document Summary
Inference judgment based on evidence or assumptions or reasons. Poll says 85% of people will vote for one political party and you draw the conclusion that the"ll win. An argument consists of two things: a group of one or more sentences the premises, one further sentence the conclusion. Argument also make a claim -> conclusion. Sometimes premises are called reasons or assumptions. Each sentence in an argument can either be true or false. (declarative) In real life we think of arguments as two people fighting a dispute or disagreement but for critical reasoning, an argument is just a group of declarative sentences, one is the conclusion and the rest are premises. We often use arguments for problem solving or deliberation (long and careful consideration or discussion) In these situations, we"re not justifying a claim, rather we are thinking about what would happen if we did certain things or if certain events occurred.
