From the summit of this hill, there is a prospect unequalled by any to be seen from the midst of a great city. Westward lies the Forth, and beyond it, dimly blue, the far away Highland hills; eastward, rise the bold contours of Arthur's Seat and the rugged crags of the Castle rock, with the grey Old Town of Edinburgh; while, far below, from a maze of crowded thoroughfares, the hoarse murmur of the toil of a polity of energetic men is borne upon the ear. At times, a man may be as solitary here as in a veritable wilderness; and may meditate undisturbedly upon the epitome of nature and of man--the kingdoms of this world--spread out before him. Surely, there is a fitness in the choice of this last resting-place by the philosopher and historian, who saw so clearly that these two kingdoms form but one realm, governed by uniform laws and alike based on impenetrable darkness and eternal silence: and faithful to the last to that profound veracity which was the secret of his philosophic greatness, he ordered that the simple Roman tomb which marks his grave should bear no inscription but DAVID HUME BORN 1711. DIED 1776. _Leaving it to posterity to add the rest._ It was by the desire and at the suggestion of my friend, the Editor of this Series, that I undertook to attempt to help posterity in the difficult business of knowing what to add to Hume's epitaph; and I might, with justice, throw upon him the responsibility of my apparent presumption in occupying a place among the men of letters, who are engaged with him, in their proper function of writing about English Men of Letters. That to which succeeding generations have made, are making, and will make, continual additions, however, is Hume's fame as a philosopher; and, though I know that my plea will add to my offence in some quarters, I must plead, in extenuation of my audacity, that philosophy lies in the province of science, and not in that of letters. In dealing with Hume's Life, I have endeavoured, as far as possible, to make him speak for himself. If the extracts from his letters and essays which I have given do not sufficiently show what manner of man he was, I am sure that nothing I could say would make the case plainer. In the exposition of Hume's philosophy which follows, I have pursued the same plan, and I have applied myself to the task of selecting and arranging in systematic order, the passages which appeared to me to contain the clearest statements of Hume's opinions.
