Courage and cowardice are antithetical. Courage is an inner resolution to go forward in spite of obstacles and frightening situations; cowardice is a submissive surrender to circumstance. Courage breeds creative self-affirmation; cowardice produces destructive self-abnegation. Courage races fear and thereby masters it; cowardice represses fear and is thereby mastered by it. Courageous men never lose the zest for living even though their life situation is zestless; cowardly men, overwhelmed by the uncertainties of life, lose the will to live. We must constantly build dykes of courage to hold back the flood of fear. – Martin Luther King, Jr.
