Commentary Par IV 130-132

Tozer (DDP Tozer.Par.IV.130-132) explains this difficult text as follows: '"owing to this desire of knowing the Divine Verity, doubt arises at the foot of truth as saplings rise from the foot of a tree."  Appiè del vero: this is another way of saying that it springs from the root of truth, that idea being suggested by the metaphor: the doubt is a germ of truth, è natura, &c.: "it is a natural process, which impels us from height to height unto the summit."  By the questions which arise from learning a truth, we are led on to the apprehension of a higher truth, and so onwards till the highest is reached.'
