But the lover of intelligence must be patient with those who cannot readily share his passion. Some pangs the mind will inflict upon the heart. It is a mistake to think that men are united by elemental affections. Our affections divide us. We strike roots in immediate time and space, and fall in love with our locality, the customs and the language in which we were brought up. Intelligence unites us with mankind, by leading us in sympathy to other times, other places, other customs; but first the prejudiced roots of affection must be pulled up. These are the old pangs of intelligence, which still comes to set a man at variance against his father, saying, “He that loveth father or mother more than me, is not worthy of me.â€
