Document Summary
Argument forms (valid, invalid, sound, unsound, strong, weak, cogent uncogent) Inductive (strong, weak, cogent, uncogent (probabilistic)) - those where there is not, and there is not intended to be, a necessary inferential relationship between premises and conclusion, only a probable inferential relationship. The conclusion only likely follows from the truth of the premises (in a strong inductive argument). Weak inductive - unlikely that conclusion follows from the premises. Example: every crow we have observed in the past twenty years is black. Deductive (valid, invalid, sound, unsound) - one where there is intended to be a necessary inferential relationship between premises and conclusion. An argument can be valid and have valid form, but the conclusion does not necessarily have to be true. If carol did that all by herself, then elephants can fly. Valid - a valid argument is under the assumption that all premises are true, the conclusion must be true.
