7. There were two pillars put at the entrance of Solomon's temple, one on the right hand and the other on the left: that which was on the right hand he called, according to the Septuagint, _Direction_, [Greek: katorthosis], and that on the left hand, _Strength_, [Greek: ischus]. (2 Par. iii. 17.) Further we are told that Solomon set seventy thousand men to carry burdens on their shoulders, and eighty thousand to hew stones in the mountains, and three thousand six hundred to be overseers of the work of the people. (2 Par. ii. 18.) The history is manifest. Strength and Direction build the Temple: Strength, or Manual Labour, represented by the hodmen and quarrymen, and the rest of the "hands:" Direction, or Mental Labour, represented by the overseers. Yet not by them alone: surely we must count in as doers of mental labour the designer of the Temple, or at least of its decorations, that "most wise and skilful man, my father Hiram;" and still more King Solomon himself and David, the two royal minds that originated and perfected the idea; and David's generals, Joab and Banaias, who secured the peace that was necessary as a condition of the building; and innumerable other men of place and power in the nation, but for whose thought and prudence the strength of the workman would have been thrown away like a river poured out in the Libyan desert. From this example, eked out with a little thought of his own, the reader may estimate the wisdom and credit of those who tell factory hands that it is their labour which produces all the wealth of their employer, and that, in the day when every man shall receive his due, the employer shall be made a workmen like themselves, and his wealth shall go to the increase of their common wages. 8. Certainly, it will be said, the employer should be paid for his mental labour, but why at so enormously higher a rate than the manual labourers? If we say, "because his labour is more valuable," some Socialists would join issue on the score that labour is valuable according to the time that it takes, and the employer works shorter hours than his men. But this taking account of _quantity_ alone in labour is an ignoring of the distinction which we have drawn of two _qualities_ or _orders_ of labour, mental and manual; one more valuable than the other as being scarcer and in greater demand, so that a short time of one may be set against a long time of another, like a little gold against a heap of brass. Any man accustomed to both orders of labour must have observed, that while he can work with his hands at almost any time when he is well, the highest labour of his intellect can be done only at rare intervals, and that in one happy hour he will sometimes accomplish more than in a day. As the same man differs from himself at different times, so does one man from another in the average value of his mental efforts: this value is not measured by time.
