The definition in this article should probably be clarified since, I'm assuming, in the statement "A unless B", A is not called the antecedent even though it comes first, because logically, the statement is equivalent to "if not B then A". Thus A is actually the consequent. Right? - dcljr (talk) 20:51, 15 January 2011 (UTC)
- True, referring to "first" and "second" is not a good definition (one also occasionally says "B if A"). Regarding unless, doesn't the statement mean "(not A) if and only if B"? AmirOnWiki (talk) 10:21, 16 November 2013 (UTC)
I can't figure out why the author of this paragraph (copied and pasted below) changed alphabets. If there is some meaning conveyed by switching from the Latin P and Q to the Greek φ and ψ, then that should be clarified. If not, I think it would be better to select one set of symbols and stick with it.
- This is a nonlogical formulation of a hypothetical proposition. In this case, the antecedent is P, and the consequent is Q. In an implication, if φ implies ψ then φ is called the antecedent and ψ is called the consequent.
