What has the author Clifton O Dummett written?

There doesn't appear to be an author named "Clifton O Dummett." It's possible there's a typo in the name.

Are you perhaps thinking of:

* Michael Dummett, a renowned philosopher who wrote extensively on logic, philosophy of language, and the philosophy of mathematics?

* Clifton Fadiman, a well-known literary critic and anthologist?

If you could clarify the name, I can help you find information about their writings.
