“The actuality of Nature is like the beauty of Nature. We can scarcely describe the beauty of a landscape as non-existent when there is no conscious being to witness it; but it is through consciousness that we can attribute a meaning to it. And so it is with the actuality of the world. If actuality means ‘known to mind’ then it is a purely subjective character of the world; to make it objective we must substitute ‘knowable to mind’.”
