" I am speaking here of things we have consciously seen or heard, and subsequently forgotten. But we all see, hear, smell, and taste many things without noticing them at the time, either because our attention is deflected or because the stimulus to our senses is too slight to leave a conscious impression. The unconscious, however, has taken note of them, and such subliminal sense perceptions play a significant part in our everyday lives. Without our realizing it, they influence the way in which we react to both events and people. "
