Mentalese

In the wonderful book, The Language Instinct, Steven Pinker makes an argument that our thoughts are not represented as words inside our head. As evidence, he states:
We have all had the experience of uttering or writing a sentence, then stopping and realizing that it wasn't exactly what we meant to say.

This is how I feel each time I post. Or, to paraphrase Moshe Rabbeinu - I've got uncircumcized lips!
