"One plants the tree, but eh, the slow-grown shade
His grandchild will enjoy."[69]
And when you look with pleased wonder at some swiftly flowing stream, then, that I bring no other poet's thought, keep ever in mind this one of your own—
"No river harries with more rapid flight
Than Life's swift current."[70]
Neither let multitude of days or the artificial divisions of time deceive your judgment; for man's whole existence, let it be never so prolonged, Is but as one day, and that not a day entire.
Have oftentimes before your eyes one similitude of Aristotle's, whom I know to be a favourite of yours; and his words I am sure you never read or hear without feeling them deeply. You will find it reported by Cicero in the Tusculan Orations, and in words possibly even more clear and impressive than the original. Here is what he says, or very nearly so, for at the moment I have not his book at hand:—
"Aristotle tells us that on the banks of the river Hypanis, which on one side of Europe empties itself into the Euxine Sea, there exists a race of little animals who only live one day. Any one of them that dies at sunrise dies young; he that dies at noon is middle-aged; and should one live till sunset, he dies in old age: and especially is this so about the time of the solstice. If you compare the time of man's life with eternity, it will seem no longer than theirs."[71] So far I give you Cicero; but what he says seems to me so beyond all cavil that now for a long time the saying has passed from the tongue of philosophers into common speech. Every day you hear even ignorant and unlearned men, if they chance to see a little child, make use of some expression like this—"Well, well, it's early morning with him yet"; if they see a man they will say, "Oh, it's high noon with him now," or "He's well in the middle of his day"; if they see one old and broken down they will remark, "Ah! he's getting toward evening and the going down of the sun."
Ponder well on these things, my very dear son, and on others akin to them, which will, I doubt not, flock into your thoughts, as these on the spur of the moment have come into mine. And one more thing I beseech you to have in mind: look at the graves of those older, perhaps, than you, but whom nevertheless you have known; look diligently, and then rest assured that the same dwelling-place, the same house, is for you also made ready. Thither are all of us travelling on; that is our last home. You who now, perchance, are proud and think that your springtime has not quite departed, and are for trampling others underfoot, you in turn shall underfoot be trampled. Think over all this; consider it by day and by night; not merely as a man of sober mind and remembering what nature he is of, but as becomes a man of wisdom, and so holding it all fast, as one who remembers it is written
"A wise man's life is all one preparation for death."[72]
This saying will teach you to think little of what concerns earthly things, and set before your eyes a better path of life on which to enter. You will be asking me what is that kind of life, and by what ways you can approach it? And I shall reply that now you have no need of long advice or counsel. Listen only to that Holy Spirit who is ever calling, and in urgent words saying, "Here is the way to your native country, your true home."
You know what He would bring to mind; what paths for your feet, what dangers to avoid. If you would be safe and free obey His voice. There is no need for long deliberations. The nature of your danger calls for action, not words. The enemy is pressing you from behind, and hastening to the charge in front; the walls of the citadel, where you are besieged, already tremble. There is no time for hesitation. Of what use is it to make sweet songs for the ears of others, if you listen not to them yourself?
