Are labour and self-culture irreconcilable to each other? In the first place, we have seen that a man, in the midst of labour, may and ought to give himself to the most important improvements, that he may cultivate his sense of justice, his benevolence, and the desire of perfection. Toil is the school for these high principles; and we have here a strong presumption that, in other respects, it does not necessarily blight the soul. Next, we have seen that the most fruitful sources of truth and wisdom are not books, precious as they are, but experience and observation; and these belong to all conditions. It is another important consideration, that almost all labour demands intellectual activity, and is best carried on by those who invigorate their minds; so that the two interests, toil and self-culture, are friends to each other. It is mind, after all, which does the work of the world, so that the more there is of mind, the more work will be accomplished. A man, in proportion as he is intelligent, makes a given force accomplish a greater task; makes skill take the place of muscle, and with less labour, gives a better product. Make men intelligent, and they become inventive; they find shorter processes. Their knowledge of nature helps them to turn its laws to account, to understand the substances on which they work, and to seize on useful hints, which experience continually furnishes. It is among workmen that some of the most useful machines have been contrived. Spread education, and as the history of this country shews, there will be no bounds to useful invention.--_Channing._ * * * * * Printed and Published by W. and K. CHAMBERS, High Street, Edinburgh.
