Ps and Qs =[edit]

I am just wondering whether the Ps and Qs of the section Philosophy_of_logic#Analytic_Truths.2C_Logical_truth.2C_Validity.2C_Logical_consequence_and_Entailment need to be explained. I would think that p is used for proposition and wondered whether q, in the current sense, might also relate to qualia.

p and q with or without subscript are being used as propositional variables— Philogos (talk) 01:44, 18 July 2011 (UTC)
