When a man may be spoken with, not to speak to him is to err in reference to the man. When a man may not be spoken with, to speak to him is to err in reference to our words. The wise err neither in regard to their man nor to their words.
[tr. Legge (1861), 15.7]

Not to speak to a man to whom you ought to speak, is to lose your man; to speak to one to whom you ought not to speak is to lose your words. those who are wise will not lose their man, nor yet their words.
[tr. Jennings (1895), 15.7]

When you meet the proper person to speak to and do not speak out, you lose your opportunity; but when you meet one who is not a proper person to speak to and you speak to him, you waste your words. A man of intelligence never loses his opportunity, neither does he waste his words.
[tr. Ku Hung-Ming (1898), 15.7]

Not to enlighten one who can be enlightened is to waste a man; to enlighten one who cannot be enlightened is to waste words. The intelligent man neither wastes his man nor his words.
[tr. Soothill (1910), 15.7]

When you should talk to a man, and don’t, you lose the man; when it’s no use talking to a man, and you talk to him, you waste words. An intelligent man wastes (loses) neither men nor words.
[tr. Pound (1933), 15.7]

Not to talk to one who could be talked to, is to waste a man. To talk to those who cannot be talked to, is to waste one's words. He who is truly wise never wastes a man; but on the other hand, he never wastes his words.
[tr. Waley (1938), 15.7]

If we fail to speak with a man who can be spoken with, we lose a man. If we do speak with a man who cannot be spoken with, our words go for nought. The wise lose neither man nor words.
[tr. Ware (1950), 15.8]

When you find a person worthy to talk to and fail to talk to him, you have lost your man. When you find a man unworthy to talk to and you talk to him, you have lost (i.e., wasted) your words. A wise man neither loses his man, nor loses his words.
[tr. Lin Yutang (1938)]

To fail to speak to a man who is capable of benefiting is to let a man go to waste. To speak to a man who is incapable of benefiting is to let one's words go to waste. A wise man lets neither men nor words go to waste.
[tr. Lau (1979), 15.8]

When dealing with a man who is capable of understanding your teaching, if you do not teach him, you waste the man. When dealing with a man who is incapable of understanding your teaching, if you do teach him, you waste your teaching. A wise teacher wastes no man and wastes no teaching.
[tr. Leys (1997), 15.8]

If a man is worth talking to and you do not talk to him, you lose a man; if a man is not worth talking to and you talk to him, you lose your words. The man of wisdom neither loses a man nor loses his words.
[tr. Huang (1997), 15.8]

When you should talk with one, you do not talk with one, it means to lose the people. When you should not talk with one, you talk with one, it means to lose the word. A wise person does not lose the people, and does not lose the word too.
[tr. Cai/Yu (1998), 15.8 / #392]

When it is appropriate and feasible to speak [and give advice] to a person, but you refrain from doing so, you will lose a friend. When it is inappropriate or infeasible to speak to a person, but you speak anyhow, you misspeak.
[tr. Li (2020), 15.8]

Many fetch a tedious compass of words, without ever coming to the knot of the business: they make a thousand turnings and windings, that tire themselves and others, without ever arriving at the point of importance. And that proceeds from the confusion of their understanding, which cannot clear it self. They lose time and patience in what ought to be let alone, and then they have no more to bestow upon what they have omitted.
[Flesher ed. (1685)]

Many lose their way either in the ramifications of useless discussion or in the brushwood of wearisome verbosity without ever realising the real matter at issue. They go over a single point a hundred times wearying themselves and others and yet never touch the all important centre of affairs. This comes from a confusion of mind from which they cannot extricate themselves. They waste time and patience on matters they should leave alone and cannot spare them afterwards for what they have left alone.
[tr. Jacobs (1892)]

Most roam around, in useless millings either about the edge, or in the scrub of a tiresome verbosity, without striking upon the substance of the matter, they make a hundred turns about a point, wearying themselves, and wearying others, yet never arriving at the centre of what is important,- it is the product of a scattered brain that does not know how to get itself together,- they spend time, and exhaust patience, over that which they should leave alone, and afterwards are short of both for what they did leave alone.
[tr. Fischer (1937)]

Disgraceful 't is unto a poet's name
Difficult toys to make his highest am:
The labour's foolish that doth rack the brains
For things have nothing in them, but much pains.
[tr. Killigrew (1695)]

How foolish is the toil of trifling cares.
[tr. Johnson (1750); he credits the translation Elphinston]

How pitifull the boast of petty feats!
How idle is the toil of mean conceits!
[tr. Elphinston (1782), 2.76]

It is disgraceful to be engaged in difficult trifles; and the labour spent on frivolities is foolish.
[tr. Amos (1858), 2.19]

It is absurd to make one's amusements difficult; and labor expended on follies is childish.
[tr. Bohn's Classical (1859)]

'Tis mean and foolish to assign
Long care and pains to trifles light.
[tr. Webb (1879)]

Disgraceful ’tis to treat small things as difficult;
‘Tis silly to waste time on foolish trifles.
[ed. Harbottle (1897)]

'Tis degrading to undertake difficult trifles; and foolish is the labour spent on puerilities.

And labor lost to work at nonsense prose.
