There is no doubt that physical unsoundness often is a cause of mental excellence. Some of the best women on earth are the ugliest. Their ugliness cut them off from the enjoyment of the gaieties of life; they did not care to go to a ball-room and sit all the evening without once being asked to dance; and so they learned to devote themselves to better things. You have seen the pretty sister, a frivolous, silly flirt; the homely sister, quietly devoting herself to works of Christian charity. Ugly people, we often hear it said, cry up the beauties of the mind. It may be added, that ugly people possess a very large proportion of those beauties. And a great deal of the best intellectual work is done by men who are physically screws; by men who are nearly blind, broken-winded, lame, and weakly. We all know what the Apostle Paul was physically; we know too what the world owes to that dwarfish, bald, stammering man. I never in my life read anything more touching than the story of that poor weakly creature, Dr. George Wilson, the Professor of Technology in the University of Edinburgh. Poor weakly creature, only in a physical sense; what a noble intellectual and moral nature dwelt within that slender frame! You remember how admirably he did his work, though in a condition of almost ceaseless bodily weakness and suffering; how he used to lecture often with a great blister on his chest; how his lungs and his entire system were the very poorest that could just retain his soul. I never saw him; but I have seen his portrait. You see the intellectual kindly face; but it is but the weakly shadow of a physical man. But it was only physically that George Wilson was a poor type of humanity. What noble health and excellence there were in that noble mind and heart! So amiable, so patient, so unaffectedly pious, so able and industrious; a beautiful example of a great, good, memorable and truly loveable man. Let us thank God for George Wilson: for his life and his example. Hundreds of poor souls ready to sink into morbid despair of ever doing anything good, will get fresh hope and heart from his story. It is well, indeed, that there have been some in whom the physical system equals the moral; men like Christopher North and Sydney Smith,--men in whom the play of the lungs was as good as the play of the imagination, and whose literal heart was as excellent as their metaphysical. We have all seen examples in which the noblest intellect and kindest disposition were happily blended with the stoutest limbs and the pleasantest face. And the sound mind in the sound body is doubtless the perfection of the human being. I have walked many miles and many hours over the heather, with one of the ablest men in Britain: a man whom at fourscore his country can heartily trust with perhaps the gravest charge which any British subject can undertake. And I have witnessed with great delight the combination of the keenest head and best heart, with physical
