Context

“This place ought not to be passed over without a remark upon the vanity of so great a man; for besides that these considerations are infinitely light in themselves, the last is only a proof to the Greeks that they have their souls lodged in that part. No human judgment is so sprightly and vigilant that it does not sometimes sleep. Why do we fear to say? The Stoics, the fathers of human prudence, think that the soul of a man, crushed under a ruin, long labours and strives to get out, like a mouse caught in a trap, before it can disengage itself from the burden.” source
