The simple faith which beat in the life of the Bathgate baker's household was ingrained into James Simpson; he went forth into the world full of it, and full of the determination that by his fruits he should be known. The tender, loving care for his welfare of his sisters and brothers, particularly of Sandy, who never faltered in his inspired belief in James's great future, kept alive in Simpson something of his mother's affectionate nature, and kindled the sympathies and emotions which bulked so large in his character. His goodness was displayed in his kindly treatment of the poor, who formed at first the whole and afterwards no small part of his patients. When name and fame and bread were his, he did not turn his back on the poor, but as we have seen, ever placed his skill at their disposal for no reward, as readily as he yielded it to the greatest in the land. As in his daily practice, so in his greatest professional efforts, the revelation of chloroform, the fight for anaesthesia, the introduction of acupressure, the crusade against hospitalism, one thought breathed through his work--that he might do something to better the condition of suffering humanity. He never attempted to keep discoveries in his own hands, to profit by the monopoly, but scattered wide the knowledge which had come to him that it might benefit mankind and grow stronger and wider in the hands of other workers. In his domestic life he was a tender, loving, and companionable husband and father, a charming host, and a warm-hearted friend. "In this Edinburgh of ours," says a recent writer, "there are familiar faces whose expression changes greatly at the mention of his name; there are men whose speech from formal and precise turns headlong and extravagant, as if it came from a new and inspired vocabulary." In Scotland his personal influence was immense. As was afterwards written of him, "Great in his art, and peerless in resource, yet greater was he in his own great soul;" such a man stood in no need of the violent revolution in mode of life implied in conversion. A gradual process of development led to his feeling that although to labour was to pray, there was a need for more attention to the spiritual, even in his self-sacrificing life. There is evidence that during a brief period of his career Simpson became affected by speculative doubts; indeed it would have been surprising if his mind had not been affected by some of the new schools of thought which sprang up in the footsteps of Charles Darwin, and appeared for a time to threaten a mortal antagonism to all that was dear to orthodox Christians. But these did not influence him long; true to his character he examined every new thought and finding it wanting remained firm in his old and tried faith, and ranged himself on the side of those who perceived nothing seriously incompatible between religion and modern science.
