Document Summary
Cogent-convincing/persuasive/rationally believable, argument is cogent when it provides sufficient grounds for the rational belief of its conclusion. Strongly cogent argument- provides high degree of justification for its conclusion. Weaker cogent argument-only a tentative or easily overturned justification. A lot of arguments that are cogent but not valid. Deductively sound argument is fully cogent by these definitions: w/ true premises and valid structure, it demonstrates truth of conclusion. Argument can be even strongly cogent but unsound these provide high degree of support for conclusion despite not being deductively valid. Cogent example my daughter has small red itchy bumps on her body, she is cranky, has a slight fever, and she has chicken pox (counter examples: could be chicken pox, spider bites, small pox, etc. ) Fallacies- arguments that are presented as if valid and only would be cogent if they were valid. Enthymemes- valid with one or more premises unstated (audience is supposed to understand from context)
