Collected Works of George Gissing on Charles Dickens

the long version

One thing to be learnt from every page of the biography is the strenuous spirit in which Dickens wrought. Whatever our judgment as to the result, his zeal and energy were those of the born artist. Passages numberless might be quoted from his letters, showing how he enjoyed the labour of production, how he threw himself into the imaginative world with which he was occupied, how impossible it was for him to put less than all his splendid force into the task of the moment.
