It seems to me that we might add another notion to the notions of Types and Tokens which we were discussing last time in class. If we consider the type:
We can say that there are three tokens of it below:
A A A
But consider a case of the type •red• (where I will put types in dots, I hope that there are dots there, following Sellars to bring attention to the 'role' that this word plays and not to the English word token 'red' or to the inscription *red*):
red red rouge rot
It would seem here that we still have one type in play, the •red• type. Those four words above all mean what 'red' means (in English). Roughly, 'red', 'rouge' and 'rot' all mean the same thing. But it seems that we have three distinct kinds of tokens: there are two English tokens, one French token and one German token.
With something like this in mind, Sellars has a notion of Token-class. We can say that there is one type above, but three token-classes: the English 'red', tokened twice; the French 'rouge' tokened once; and the German 'rot' tokened once.
I hope that I have done an adequate job of spelling out the position. Does it prove to be helpful?
