Not really. In the end, the words have to be related to actions. This relates to your other question about symbols.
Words are just symbols, but we can never be sure we know what the other person means when they use a word. The only way to gain any clarity on this is if a person’s words and actions are consistently related in the same way. Symbols are used for communication, and I guess they can communicate intentions and they can communicate why intentions may not get carried out.
But in the end it is actions (or lack thereof) that we must deal with. For some people, having the symbol may be enough. The symbol is an action as well as a symbol. But for most people, in the end, it is the action that is truly meaningful. So in this sense, words are not enough. Only actions can show what one really intends.
