"Through ages unfriended, With sophistry blended, Deep science in Chaos had slept; Its limits were fettered, Its voters unlettered, Its students in movements but crept. Till, despite of great foes, Great WALSH first arose, And with logical might did unravel Those mazes of knowledge, Ne'er known in a college, Though sought for with unceasing travail. With cheers we now hail him, May success never fail him, In Polar Geometrical mining; Till his foes be as tamed As his works are far-famed For true philosophic refining." Walsh's system is, that all mathematics and physics are wrong: there is hardly one proposition in Euclid which is demonstrated. His example ought to warn all who rely on their own evidence to their own success. He was not, properly speaking, insane; he only spoke his mind more freely than many others of his class. The poor fellow died in the Cork union, during the famine. He had lived a happy life, contemplating his own perfections, like Brahma on the lotus-leaf.[594] {265} GROWTH OF FREEDOM OF OPINION. The year 1825 brings me to about the middle of my _Athenaeum_ list: that is, so far as mere number of names mentioned is concerned. Freedom of opinion, beyond a doubt, is gaining ground, for good or for evil, according to what the speaker happens to think: admission of authority is no longer made in the old way. If we take soul-cure and body-cure, divinity and medicine, it is manifest that a change has come over us. Time was when it was enough that dose or dogma should be certified by "Il a ete ordonne, Monsieur, il a ete ordonne,"[595] as the apothecary said when he wanted to operate upon poor de Porceaugnac. Very much changed: but whether for good or for evil does not now matter; the question is, whether contempt of _demonstration_ such as our paradoxers show has augmented with the rejection of _dogmatic authority_. It ought to be just the other way: for the worship of reason is the system on which, if we trust them, the deniers of guidance ground their plan of life. The following attempt at an experiment on this point is the best which I can make; and, so far as I know, the first that ever was made.
