Intelligence is derived from two words; inter and legere. Inter meaning ‘between’ and legere meaning ‘to choose’. An intelligent person, therefore, is one who has learned ‘to choose between’. He knows that good is better than evil, that confidence should supersede fear, that love is superior to hate, that gentleness is better than cruelty, forbearance than intolerance, compassion than arrogance, and that truth has more virtue than ignorance.

– J. Martin Klotsche
