Abstract
In this paper, I'll consider the problem about, “Communication and Convention” given by Davidson and Wittgenstein. In considering this problem, Davidson distinguish “literal meaning (what words means)” and “what speakers means”. And He says that we have to interpret a speaker to know the latter but the way of interpreting a speaker depends on no rule stated in advance. If that so, the significance of rule or convention in our linguistic communication would disappear. Through considering “Our form of life”, I'll discuss this problem.
