“ We should always be learners, gladly welcoming every help, and respecting every personality. But we should also respect our own, and bear in mind, that "though the wide universe is full of good, no kernel of nourishing corn can come to us but through our toil bestowed on that plot of ground which is given to us to till." To undervalue our own thought because it is ours, to depreciate our own powers or faculties because some one else's are more vigorous, to shrink from doing what we can because we think we can do so little, is to hinder our own development and the progress of the world. ”
