Be it of love, hate, of pleasure, of suffering, of imagination, or all other states of mind, sentiment or sickness; the process depends in every case on the chemical reactions produced in the interior of the brain, and the resulting electrical impulses or messages, be they visual, auditory, based on memory, or an interpretation of new events based on elements that one has in the memory.
