acknowledged, and long since consigned to the rubbish of oblivion. Yet all have claim to the common apology, _false scientific education_, excepting those who have assented to what they have seen with wonder, and afterwards denied their admission. The established philosophy cannot account for the boy's marble going farther through the air than the fullest extent of the impelling thumb. The proposition may appear trifling and insignificant, yet is it worthy the consideration of the Chair of Knowledge, from which it has never been explained nor there understood, as involving the cause of planetary motion; for, _in all nature there are not two causes of motion_. That the marble "_partakes_" of the _force_, and "partakes" of the _motion_ of that by which it is impelled, is an absurd idea; the force and motion of a body were not, and cannot become, the force and motion of any other body. The established philosophy cannot account for the splinters of a stone having motion out of the direction of impulse, nor for having motion in every direction but that of the stone-breaker's impelling hammer, which appears at variance with the natural, immutable dynamic law, which says, that _as a body cannot move itself_, so must it have motion in the direction only of that by which it is being moved. Neither is there any philosophy extant, which explains why the stone at Texteth of one hundred tons should rise, as if of itself, six inches in the air, under which the quarrymen could have shoved a hand and withdrawn it safely, before the immense mass fell crushingly on the former bed. On the other hand, what the established philosophy undertakes to explain, it explains erroneously. Beside maintaining the transfer of a local casualty, in accounting for continuous motion, it teaches that the power of steam consists in heat, and that cold congeals water: whereas heat and cold have no physical existence; each is a sensation, anything similar to which it is impossible for either fire or water to possess. So that to the present day the power of steam, the cause of combustion and of congelation has in each instance remained unknown.
