I call a man fanatical when his enthusiasm is narrow and hoodwinked, so that he has no sense of proportions, and becomes unjust and unsympathetic to men who are out of his own track.

Context

“I suppose I heard a little too much preaching in my youth and lost my palate for it." "I don't think you will find that Mordecai obtrudes any preaching," said Deronda. "He is not what I should call fanatical. I call a man fanatical when his enthusiasm is narrow and hoodwinked, so that he has no sense of proportions, and becomes unjust and unsympathetic to men who are out of his own track. Mordecai is an enthusiast; I should like to keep that word for the highest order of minds—those who care supremely for grand and general benefits to mankind. He is not a strictly orthodox Jew, and is full of allowances for others;” source
