from the Newsletter of the Multidisciplinary Association for Psychedelic Studies. MAPS - Volume 4 Number 2 Summer 1993 - pp 47-49. The Great Entactogen - Empathogen Debate. I write to respond to the letter from Ralph Metzner regarding the name empathogen versus entactogen [for drugs such as MDMA]. I did tell Ralph that I believed that the pronunciation em-PATH'-o-gen would create a negative impression in the mind of a psychiatric patient, because of the distinct embodiment of the word 'pathogen' within the name.

Market Demand. Market demand provides the total quantity demanded by all consumers. In other words, it represents the aggregate of all individual demands. There are two basic types of market demand: primary and selective. Primary demand is the total demand for all of the brands that represent a given product or service, such as all phones or all high-end watches.
