Chrysippus's Solution to the Sorites Paradox

Chrysippus was apparently the first to feel this fascination. He wrote entire treatises on the paradox, and thus has some claim to be the first philosopher to deal with the topic of vagueness. Sadly, these works are lost. We know only from later reports that his way out of the paradox was this, simply fall silent before it becomes unclear whether the sand is a heap. If things start being unclear at about 25 grains, then when you are asked about the twentieth grain of sand, just say nothing at all, refuse to be drawn on the issue.
