Isaac the Syrian: “These are the causes of sin”

This is from the blog Dover Beach:

“Whoever does not voluntarily withdraw himself from the causes of the passions is involuntarily drawn away by sin. These are the causes of sin: wine, women, riches, and robust health of body. Not that by their nature these things are sins, but that nature readily inclines towards the sinful passions on their account., and for this reason man must guard himself against them with great care.”
