But even the above phases of memory represent but a small segment of its complete circle. Memory is more than "a good memory"--it is the means whereby we perform the largest share of our mental work. As Bacon has said: "All knowledge is but remembrance." And Emerson: "Memory is a primary and fundamental faculty, without which none other can work: the cement, the bitumen, the matrix in which the other faculties are embedded. Without it all life and thought were an unrelated succession." And Burke: "There is no faculty of the mind which can bring its energy into effect unless the memory be stored with ideas for it to look upon." And Basile: "Memory is the cabinet of imagination, the treasury of reason, the registry of conscience, and the council chamber of thought." Kant pronounced memory to be "the most wonderful of the faculties." Kay, one of the best authorities on the subject has said, regarding it: "Unless the mind possessed the power of treasuring up and recalling its past experiences, no knowledge of any kind could be acquired. If every sensation, thought, or emotion passed entirely from the mind the moment it ceased to be present, then it would be as if it had not been; and it could not be recognized or named should it happen to return. Such an one would not only be without knowledge,--without experience gathered from the past,--but without purpose, aim, or plan regarding the future, for these imply knowledge and require memory. Even voluntary motion, or motion for a purpose, could have no existence without memory, for memory is involved in every purpose. Not only the learning of the scholar, but the inspiration of the poet, the genius of the painter, the heroism of the warrior, all depend upon memory. Nay, even consciousness itself could have no existence without memory for every act of consciousness involves a change from a past state to a present, and did the past state vanish the moment it was past, there could be no consciousness of change. Memory, therefore, may be said to be involved in all conscious existence--a property of every conscious being!"
