Mescaline: similar enough that it can invade the synapses and stimulate. Rene descartes- cogito, ergo sum (i think, therefore i am) Emmanuel kant"s distinction between the noumenon (thing-in-itself) and phenomenon (thing as it happens) Proximal stimulus: pattern of energy falling on sense receptor. Percept ( reality ): our experience of a stimulus. John locke"s distinction between primary and secondary qualities.
