In terms, asoulism (CR:5) (LH:5) (TL:10), from a- meaning "not, without, or opposite", + soul meaning "ba or anima", + -ism meaning "doctrine or idea", refers to disbelief in the existence of the soul. The term was coined in 2010 by David Weisman. An "asoulist" is person who does not believe in the existence of the soul.
Historically, the first to officially declare that the "soul" does not exist was: Jean Meslier (1729). Following Meslier, we have: Julien Mettrie (1745), Francois Broussais (c.1820), and Thomas Edison (1824); not to mention a few recent thinkers: Kurt Bell (2011), Patrick Fergus (2014), and Libb Thims (2015).
The following are quotes:
- “The same cast of mind which caused Gassendi to detach the creator from his universe led him also to detach the soul from the body, though to the body he ascribes an influence so large as to render the soul almost unnecessary.”
- “I wish there were a term in the English language that honestly captures the idea that all we experience is due to brain function. ‘Materialism’ comes close, but is laden with excess metaphysical baggage. The philosopher John Searle coined ‘biological naturalism’ as a mind-body theory within philosophy, and that comes very close. ‘Asoulism’ is more modest: a simple disbelief in the existence of souls based on evidence.”

- “On my better days I regard my wife and daughter as ‘soulless bags of chemicals.’ To be fair though, I think the same of myself and all other forms of life. Souls are supernatural things beyond perception or measure, worthy only of suspended belief pending some real evidence or the giving up of the tenets of science. Chemicals we are…despite the clever animation of flesh and musings of mind brought about by the electricity of life. So why do we think more of ourselves? How are we so offended by these facts?”
