Samuel Johnson on Mind

“The mind is never satisfied with the objects immediately before it, but is always breaking away from the present moment, and losing itself in schemes of future felicity…. The natural flights of the human mind are not from pleasure to pleasure, but from hope to hope.”

“"Some," answered Imlac, "have indeed said that the soul is material, but I can scarcely believe that any man has thought it, who knew how to think; for all the conclusions of reason enforce the immateriality of mind, and all the notices of sense and investigations of science, concur to prove the unconsciousness of matter.”

“[Imlac continues] "It was never supposed that cogitation is inherent in matter, or that every particle is a thinking being. Yet, if any part of matter be devoid of thought, what part can we suppose to think? Matter can differ from matter only in form, density, bulk, motion, and direction of motion: to which of these, however varied or combined, can consciousness be annexed? To be round or square, to be solid or fluid, to be great or little, to be moved slowly or swiftly one way or another, are modes of material existence, all equally alien from the nature of cogitation. If matter be once without thought, it can only be made to think by some new modification, but all the modifications which it can admit are equally unconnected with cogitative powers."”
