Science --- the study of the physical world and how it works. The practice of science is observation and mathematics is its principle tool. Science yields understanding and, through technology, mastery of the physical world. This is not always used for good purposes.
Faith --- one’s personal inquiry into what is right and good. Many of us find our roots for this inquiry to be in religion, others in the humanities, some in their community. While the sources may be different, there are universal principles on which most of us will agree.
Philosophy --- the use of human reason to increase wisdom, the goal of which is to live a life that is right and good. This is the original intention and meaning of the word “philosophy.” Scientific understanding is a start, but faith provides the compass that points us towards the goal.
