Among the other virtues, we may also give Cleanliness a place; since it naturally renders us agreeable to others, and is no inconsiderable source of love and affection. No one will deny, that a negligence in this particular is a fault; and as faults are nothing but smaller vices, and this fault can have no other origin than the uneasy sensation which it excites in others; we may, in this instance, seemingly so trivial, clearly discover the origin of moral distinctions, about which the learned have involved themselves in such mazes of perplexity and error.
David Hume, Enquiry Concerning the Principles of Morals, Section VIII (215).
So that clears that up.
