Verse 14. To "lay up" knowledge very obviously implies that value is set upon it. Men never think of seeking and accumulating what they regard as worthless; and in proportion as an object is prized will be the degree of eagerness with which it is pursued, and of jealous vigilance, with which it is "laid up" and guarded. Thus the _miser._ With what an eye of restlessness and eager covetousness does he look after the acquisition of his heart's desires! with what delight does he hug himself upon his success!--with what avidity does he add the increase to his treasures, carefully secreting them from all access but his own! With a care incomparably more dignified and useful how does the man of science mark and record every fact and observation, whether of his own discovery and suggestion or of those of others! How he exults in every new acquisition to _his_ stores! He lays all up in his mind, or, fearful of a treacherous memory, in surer modes of record and preservation. Hints that lead to nothing at the time may lead to much afterwards. Some one in another generation may carry out into practical application, or into the formation of valuable theories, the facts and conjectures that are now, in apparent isolation, "laid up" for such possible future use. The true philosopher, to use a colloquial phrase, "has all his eyes about him." He allows nothing to escape notice, and nothing, if he can help it, to pass into oblivion. But, alas! in this respect, as in others, "the children of this world are, in their generation, wiser than the children of light."--_Wardlaw._ Who would not heedfully foresee where his arrow shall hit, before he shoot it out of his bow; lest it should destroy any person or other creature through negligence? Who would not be very circumspect and wary in discharging a piece, lest he should do mischief by it? And yet, by these, a man may affright, and not hurt; and hurt, and not kill; and kill, and not die himself; but what arrow, what shot, what artillery, what murdering piece is to be compared to the mouth of a man that is not guided by a wise and watchful forethought? Great woe is worketh unto other men, but it surely bringeth death unto himself; every word that breaketh another man's skin doth certainly break the caul of his own heart; and he that doth aim at another to give him a wound, surely cannot miss himself to violate his own life.--_Dod._
