Paul,
I wonder what has made you raise this issue
Being a linguist and a translator I have decided it for myself long ago that words cannot be without feelings, except may be for technical terms
It's not so obvious in your native language because you do not think of your native language and its mechanisms and imagery and associations that much, but when you have to choose/select the words in the foreign language that is felt strongly !
I believe people did put some feeling in most of words of any language when they first builded them. Otherwise words would fail to serve their purpose of communicating feelings as they are, they would communicate only information and we wouldn't have poetry and songs and many other wonderful phenomena based on a combination of word and feeling...
Anyway an interesting issue to discuss!
