3·For if any of these propositions is a familiar fact, there is no need even to mention it; the hearer adds it himself.
因为如果这些命题中有为人熟知的事实，则其甚至无须提及，听者会自己加上的。
4·You're absolutely right statements, and propositions can be true or false but arguments can't be true or false, arguments can only be valid or invalid.
你们的论点完全正确，命题有真假，但是论点不能或真或假，论点只能有效或无效。
5·But there are also those special Lines of Argument which are based on such propositions as apply only to particular groups or classes of things.
但也有基于命题的特殊论述方向，只用于特殊事项。
