Monday Morning Thought for the Day

Petrarch (Francesco Petrarca, 1304-1374) was a late Middle Ages/Early Renaissance Italian poet who contributed mightily to restoring classic Roman ideas to his contemporary society's body of knowledge. Here's something he wrote in De Remediis in 1366:

"Five great enemies to peace inhabit within us:
viz., avarice, ambition, envy, anger, and pride.
If those enemies were to be banished,
we should infallibly enjoy perpetual peace."
