Unclean and repulsive beasts display insight and understanding in their ability to determine the proper time to increase their kind and to come out of their dens. They also observe the season when it is necessary to flee the cold and stormy distress of winter and seek shelter under rocks, in large crags, or in the deep scar of the landslide till the time to come forth is at hand. Wild beasts that seek their food in woods or on the mountains know well how to discern the seasons; for they bear the begotten offspring while winter is most severe, so that they may bring forth their young when the grass is fresh and the summer is warm. There is a little creeping thing called the ant, which can teach thoughtful men much practical wisdom, whether they be merchants or husbandmen, kings or lesser men. It teaches kings how to build castles and fortresses; in the same way it teaches the merchants and the husbandmen with what industry and at what seasons they ought to pursue their callings; for he who has proper insight and observes carefully the activities of the ant will note many things and derive much profit from them. All other creatures, too, whether clean or unclean, rejoice in this season, and with vigilant eyes seek their food in the warm summer time so as to be able to endure more confidently the perils of a destitute winter season. Now it is this covenant between these eight winds that calls forth all the delights of earth and sky and the calm stirring of the sea according to the command and mysterious skill of Him Who ordained in the beginning that thus should all nature remain until He should change the order of things. Now if you feel that some of these matters have not yet been fully cleared up, you may continue your inquiries and ask what questions you like. ------------------------------------------------------------------------ VI THE TIDES AND THE CHANGES IN THE COURSE OF THE SUN _Son._ It was a wise thought, it seems to me, to ask those questions to which I have just received such fair replies; and I am encouraged to inquire into certain other matters, namely the waxing of the sun, the moon, and the streams or tides of the ocean,—how much and how rapidly these things wax and wane. Now these things that I have brought up for discussion are subjects which especially touch the welfare of seafaring men, and it looks to me as if they would profit much from a knowledge of these matters, since it gives insight into the right conduct of their profession. And since I intend to labor diligently in the trader’s calling, I should like very much, if it can be done, to have you explain further some of those things that I have just mentioned.
