When someone says "That seems(or does not seem) logical" it is not always easy to know how they define "logical". Is it meaningful at all? I guess the question relates to the use of something that seems to be a looser term than e.g. "deductively valid" or the like, which refers to a particular system of inference and specific rules for determining truth or falsehood of propositions. Do you have any idea as to what the term commonly refers to?
