It is a satire upon those astronomers and mathematicians who have so entirely dedicated their time to the planets, that they have been careless of their family and country, and have been chiefly anxious about the acconomy and welfare of the upper worlds. But if we consider Swift's romance in aserious light, we shall find him of opinion, that those determinations in philosophy, which at present seem to the most knowing men to be perfectly well founded and underflood, are in reality unsettled, or nncertain, and may perhaps; fome ages hence, be as much decried as the axioms of Aristotle are at this day. Sir Isaac Newton and his notions may hereafter be out of fashion. There is a kind of mode in philosophy, as well as in other things: and such modes often change more from the humour and caprice of men, than either from the unreasonable, or the illfounded conclusions of the phil sophy itself. The reasonings of some philosophers have undoubtedly better foundation than those of others: but I am of opinion, (2nd Swift secns to be in the same way of thinking,) that the most applauded philosophy, hitherto cxtant, has not fully, clearly, and certainly explained many difficulties in the phaenomena of nature. I am induced to believe, that God nay have absolutely denied us the perfect knowledge of many points in philosophy, so that we shall never arrive at that perfeótion, however certain we may suppose ourselves of having attained to it already. Upon the whole, we may say with Tully, Omnibus fire in robus, et maxime in poystis, qvid ran sit citius 4 cm quid fic, dixel im. Orrery.
