Quotations about   childhood

In a word, our moral dispositions are formed as a result of the corresponding activities. Hence it is incumbent on us to control the character of our activities, since on the quality of these depends the quality of our dispositions. It is therefore not of small moment whether we are trained from childhood in one set of habits or another; on the contrary it is of very great, or rather of supreme, importance.

[καὶ ἑνὶ δὴ λόγῳ ἐκ τῶν ὁμοίων ἐνεργειῶν αἱ ἕξεις γίνονται. διὸ δεῖ τὰς ἐνεργείας ποιὰς ἀποδιδόναι: κατὰ γὰρ τὰς τούτων διαφορὰς ἀκολουθοῦσιν αἱ ἕξεις. οὐ μικρὸν οὖν διαφέρει τὸ οὕτως ἢ οὕτως εὐθὺς ἐκ νέων ἐθίζεσθαι, ἀλλὰ πάμπολυ, μᾶλλον δὲ τὸ πᾶν.]

Or, in one word, the habits are produced from the acts of working like to them: and so what we have to do is to give a certain character to these particular acts, because the habits formed correspond to the differences of these. So then, whether we are accustomed this way or that straight from childhood, makes not a small but an important difference, or rather I would say it makes all the difference.
[tr. Chase (1847)]

And indeed, in a word, all habits are formed by acts of like nature to themselves. And hence it becomes our duty to see that our acts are of a right character. For, as our acts vary, our habits will follow in their course. It makes no little difference, then, to what kind of habituation we are subjected from our youth up; but it is, on the contrary, a matter that is important to us, or rather all-important.
[tr. Williams (1869), sec. 24]

In a word moral states are the results of activities corresponding to the moral states themselves. It is our duty therefore to give a certain character to the activities, as the moral states depend upon the differences of the activities. Accordingly, the difference between one training of the habits and another from early days is not a light matter, but is serious or rather all-important.
[tr. Welldon (1892)]

In a word, acts of any kind produce habits or characters of the same kind. Hence we ought to make sure that our acts be of a certain kind; for the resulting character varies as they vary. It makes no small difference, therefore, whether a man be trained from his youth up in this way or in that, but a great difference, or rather all the difference.
[tr. Peters (1893)]

Thus, in one word, states of character arise out of like activities. This is why the activities we exhibit must be of a certain kind; it is because the states of character correspond to the differences between these. It makes no small difference, then, whether we form habits of one kind or of another from our very youth; it makes a very great difference, or rather all the difference.
[tr. Ross (1908)]

In a word, then, states come about from activities that are similar to them. That is why the activities must exhibit a certain quality, since the states follow along in accord with the differences between these. So it makes no small difference whether people are habituated in one way or in another way straight from childhood; on the contrary, it makes a huge one -- or rather, all the difference.
[tr. Reeve (1948)]

In short, it is by similar activities that habits are developed in men; and in view of this, the activities in which men are engaged should be of [the right] quality, for the kinds of habits which develop follow the corresponding differences in these activities. So in acquiring habit it makes no small difference whether we are acting in one way or on the contrary way right from our early youth; it makes a great difference, or rather all the difference.
[tr. Apostle (1975)]

In a word, then, like activities produce like dispositions. Hence we must give our activities a certain quality, because it is their characteristics that determine the resulting dispositions. So it is a matter of no little importance what sort of habits we form from the earliest age -- it makes a vast difference, or rather all the difference in the world.
[tr. Thomson/Tredennick (1976)]

In a word, then, like states arise from like activities. This is why we must give a certain character to our activities, since it is on the differences between them that the resulting states depend. So it is not unimportant how we are habituated from our early days; indeed it makes a huge difference -- or rather all the difference.
[tr. Crisp (2000)]

And so, in a word, the characteristics come into being as a result of the activities akin to them. Hence we must make our activities be of a certain quality, for the characteristics correspond to the differences among the activities. It makes no small difference, then, whether one is habituated to this or that way straight from childhood but a very great difference -- or rather the whole difference.
[tr. Bartlett/Collins (2011)]
