Single Idea 2480

[filed under theme 18. Thought / B. Mechanics of Thought / 4. Language of Thought ]

Full Idea

Thinking can't just be in sequences of English words since, notoriously, thought needs to be ambiguity-free in ways that mere word sequences are not.

Gist of Idea

Language is ambiguous, but thought isn't

A Reaction

I think this is a strong argument in favour of (at least) propositions. Thoughts are unambiguous, but their expression need not be. Sentences could be expanded to achieve clarity.
