Tuesday's Quote

Roger Bacon (1220-1292) was a Franciscan friar and early advocate of the scientific method of inquiry. Although he wrote the following over 700 years ago, I think you'll recognize it's continuing relevance:

"There are in fact four very significant stumbling blocks
in the way of grasping the truth, which hinder every man
however learned, and scarcely allow anyone to win a
clear title to wisdom, namely, the example of weak and
unworthy authority, longstanding custom, the feeling
of the ignorant crowd, and the hiding of our own ignorance
while making a display of our apparent knowledge."
