Opinion, Doubt, Knowledge, and Belief
"On St. Thomas Aquinas’ account, belief is not simply a sentiment. Rather, it involves coming into contact with a truth and having the truth come into our minds, even though we have not directly seen or verified the proof of the statement. This is quite common. Students rightly believe what scientists tell them about the experiments that have generated contemporary scientific conclusions. It would be unreasonable for a chemistry student to verify every experiment in his chemistry textbook before accepting them. Opinion, Doubt, Knowledge, and Belief (Aquinas 101) - Fr. Dominic Legge, O.P." from Video
