Rightfully said by Socrates, only philosophy junkies would understand the value of a topic enough discussed and answers fully provided. Philosophy is considered the way of life, full of wonder and wisdom and a one-way path to gaining never- ending knowledge.

Thomas Aquinas was an Italian Dominican Friar, philosopher and Catholic priest and one of the towering figures of theology so much so that he's called Doctor Angelicus and the Doctor Communis by the Roman Catholic Church.

Within a span of 20 years, he wrote over forty books, including his masterpiece 'The Summa Theologica', where he says that perfect happiness is not possible on earth, but an imperfect happiness is.

Aquinas also sees reason and faith as two ways of knowing. "Reason" covers what we can know by experience and logic alone.

"Faith" covers what we can know by God's special revelation to us. You may also want to read [worship quotes] and Saint Patrick Quotes after this.
