MECHANICS' MAGAZINE.

JANUARY 3RD JUNE 27TH, 1857.

EDITED BY R. A. BROOMAN.

VOL. LXVI.

"It is certainly true, that as man approaches nearer to the highest end of his existence, it
must constantly become easier for him to satisfy his sensual wants-that his physical existence
must cost him less labour and care; an innumerable multitude of new discoveries and inven-
tions be made to diversify and facilitate the means of subsistence.
Nature is rude and

.........

savage without the hand of man; and it should be so, that thereby man may be forced to leave
his natural state of inactivity, and elaborate her stores; that thereby he himself, instead of a
mere product of nature, may become a free, reasonable being. He does most certainly leave it;
he plucks at all hazards the apple of knowledge, for the impulse is indestructibly implanted
within him, to be like God.
There is no salvation for man until his natural sluggish-
ness is successfully combated-until he finds all his pleasures and enjoyments in activity, and
in activity alone."-FICHTE.
