 not be too much afraid of verbal personification, 

 nor of speaking, for purposes of convenience, 

 of the three voices of Nature when we simply

 is utterly baffled practically, he may kneel in 

 prayer; when a man is penetratingly thrilled with 

 jbmotion he may be borne by its ecstasy into wor-

 tether is entirely unsatisfied with his formulae
