That the state of knowledge in any country will exert a directive influence on the general system of instruction adopted in it, is a principle too obvious to require investigation.

The accumulation of skill and science which has been directed to diminish the difficulty of producing manufactured goods, has not been beneficial to that country alone in which it is concentrated; distant kingdoms have participated in its advantages.

The public character of every public servant is legitimate subject of discussion, and his fitness or unfitness for office may be fairly canvassed by any person.

There are few circumstances which so strongly distinguish the philosopher, as the calmness with which he can reply to criticisms he may think undeservedly severe.

In mathematics we have long since drawn the rein, and given over a hopeless race.

A tool is usually more simple than a machine; it is generally used with the hand, whilst a machine is frequently moved by animal or steam power.

Another mode of accumulating power arises from lifting a weight and then allowing it to fall.

Those from whose pocket the salary is drawn, and by whose appointment the officer was made, have always a right to discuss the merits of their officers, and their modes of exercising the duties they are paid to perform.

I am inclined to attach some importance to the new system of manufacturing; and venture to throw it out with the hope of its receiving a full discussion among those who are most interestedin the subject.

The half minute which we daily devote to the winding-up of our watches is an exertion of labour almost insensible; yet, by the aid of a few wheels, its effect is spread over the whole twenty-four hours.

At each increase of knowledge, as well as on the contrivance of every new tool, human labour becomes abridged.

Perhaps it would be better for science, that all criticism should be avowed.

Telegraphs are machines for conveying information over extensive lines with great rapidity.

The economy of human time is the next advantage of machinery in manufactures.
