Excerpt from The Brain: As an Organ of Mind A lifeless object makes no appreciable response to ex ternal impressions. If we touch a rock or a stone, no answering movements follow. Day and night, summer and winter succeed one another, and yet, though inani mate objects undergo imperceptible molecular changes, they yield no active and Visible response either to diurnal or to seasonal vicissitudes. It is wholly different, as we know, with the members of the vegetable kingdom existing around and amongst these inanimate things. The seasonal changes shown by them are familiar to all. The putting forth of the leaf, the period of active growth, the bloom of flowers, the Shedding of seed, the fading and fall of leaves, are so many manifestations of an internal activity which dis play themselves with never-failing regularity.
