“We are all children until our fathers die.”

A speech of Aspasia, recounted by Socrates, as portrayed in the dialogue.
Menexenus
Context: p>Let every man remind their descendants that they also are soldiers who must not desert the ranks of their ancestors, or from cowardice fall behind. Even as I exhort you this day, and in all future time, whenever I meet with any of you, shall continue to remind and exhort you, O ye sons of heroes, that you strive to be the bravest of men. And I think that I ought now to repeat what your fathers desired to have said to you who are their survivors, when they went out to battle, in case anything happened to them. I will tell you what I heard them say, and what, if they had only speech, they would fain be saying, judging from what they then said. And you must imagine that you hear them saying what I now repeat to you:Sons, the event proves that your fathers were brave men; for we might have lived dishonourably, but have preferred to die honourably rather than bring you and your children into disgrace, and rather than dishonour our own fathers and forefathers; considering that life is not life to one who is a dishonour to his race, and that to such a one neither men nor Gods are friendly, either while he is on the earth or after death in the world below.Remember our words, then, and whatever is your aim let virtue be the condition of the attainment of your aim, and know that without this all possessions and pursuits are dishonourable and evil.For neither does wealth bring honour to the owner, if he be a coward; of such a one the wealth belongs to another, and not to himself. Nor does beauty and strength of body, when dwelling in a base and cowardly man, appear comely, but the reverse of comely, making the possessor more conspicuous, and manifesting forth his cowardice.And all knowledge, when separated from justice and virtue, is seen to be cunning and not wisdom; wherefore make this your first and last and constant and all-absorbing aim, to exceed, if possible, not only us but all your ancestors in virtue; and know that to excel you in virtue only brings us shame, but that to be excelled by you is a source of happiness to us.And we shall most likely be defeated, and you will most likely be victors in the contest, if you learn so to order your lives as not to abuse or waste the reputation of your ancestors, knowing that to a man who has any self-respect, nothing is more dishonourable than to be honoured, not for his own sake, but on account of the reputation of his ancestors.The honour of parents is a fair and noble treasure to their posterity, but to have the use of a treasure of wealth and honour, and to leave none to your successors, because you have neither money nor reputation of your own, is alike base and dishonourable.And if you follow our precepts you will be received by us as friends, when the hour of destiny brings you hither; but if you neglect our words and are disgraced in your lives, no one will welcome or receive you. This is the message which is to be delivered to our children.</p

Il n'y a point d'enfants que nous aimions davantage que ceux qui naissent de notre esprit, et desquels nous sommes père et mère tout ensemble.

Context: The true Mason labors for the benefit of those that are to come after him, and for the advancement and improvement of his race. That is a poor ambition which contents itself within the limits of a single life. All men who deserve to live, desire to survive their funerals, and to live afterward in the good that they have done mankind, rather than in the fading characters written in men's memories. Most men desire to leave some work behind them that may outlast their own day and brief generation. That is an instinctive impulse, given by God, and often found in the rudest human heart; the surest proof of the soul's immortality, and of the fundamental difference between man and the wisest brutes. To plant the trees that, after we are dead, shall shelter our children, is as natural as to love the shade of those our fathers planted.

1950s, Loving Your Enemies (Christmas 1957)
Context: Jesus is eternally right. History is replete with the bleached bones of nations that refused to listen to him. May we in the twentieth century hear and follow his words-before it is too late. May we solemnly realize that we shall never be true sons of our heavenly Father until we love our enemies and pray for those who persecute us.

Footnote: He does this because of his altruistic (parental) instinct. The higher one rises in the vertebrate scale the more altruistic one becomes. The higher vertebrates are just one mass of altruism.

You Learn by Living (1960)
Context: One's philosophy is not best expressed in words; it is expressed in the choices one makes. In stopping to think through the meaning of what I have learned, there is much that I believe intensely, much I am unsure of. In the long run, we shape our lives and we shape ourselves. The process never ends until we die. And, the choices we make are ultimately our own responsibility.
