Stage Two - Premises

primary and linking premises

  • Arguments are sets of sentences where some of those sentences, the premises, purport to establish the truth of another, the conclusion.

  • Primary premise: a premise that makes a statement about some state of affairs. This premise is what we most commonly think of as the evidence.

  • Linking premise: a premise that tells you why the primary assertion supports the conclusion.


  • Enthyememes are arguments missing a premise.

  • The missing premise is often the linking premise.

  • Identifying the missing premise will not only help you to understand argument structure, but also to identify potentially problematic assumptions in arguments.


  • Example #1 (0:00) - identifying the primary and linking premises in an argument.

  • Example #2 (X:XX) - identifying the missing premise in an enthymeme.

  • Example #3 (X:XX) - another enthymeme.
