It is assumed that we ' sense ' things that are many and different on different occasions . It is assumed further that we call many of these different ' sensa ' by the same single name , for example , ' this is grey ' , ' that is grey ' , and so on .
The statement ' if there were not in existence something other than sensa , we should not be able to do what we are able to do ( viz . , Name things ) ' can perhaps be seen as offering a truncated argument .
