Intellectual tasting of life will not supersede muscular activity. If a man should consider the nicety of the passage of a piece of bread down his throat, he would starve.
The religion which is to guide and fulfill the present and coming ages, whatever else it be, must be intellectual. The scientific mind must have a faith which is science.
For such is man: a Theological Dogma might be refuted to him a thousand times - provided however, that he had need of it, he would again and again accept it as true. Belief is always most desired, most pressingly needed where there is a lack of will. Fanaticism is the sole "volitional strength" to which the weak and irresolute can be excited, as a sort of hypnotising of the entire sensory-intellectual system.
Strenuous intellectual work and the study of God's Nature are the angels that will lead me through all the troubles of this life with consolation, strength, and uncompromising rigor.
