Questio de aqua et terra (83)

(83) Ad quartum, cum arguebatur: 'Si terra non esset inferior' etc., dico quod illa ratio fundatur in falso, et ideo nihil est. Credunt enim vulgares et physicorum documentorum ignari quod aqua ascendat ad cacumina montium et etiam ad locum fontium in forma aque; sed istud est valde puerile, nam aque generantur ibi, ut per Phylosophum patet in Metauris suis, ascendente materia in forma vaporis. (83) As to the fourth, when it was argued: 'If the earth were not lower', and the rest, I say that the argument is founded upon falsity, and is therefore nought. For the vulgar, and such as have no knowledge of physical arguments, believe that water rises to the summits of the mountains and also to the place of springs, in the form of water; but that is quite puerile, for waters are generated there (as the Philosopher shows in his Meteorics) by matter which ascends in the form of vapour.
