As incorporated into the [[theory]] of [[quantum mechanics]], this is regarded by physicists as part of the fundamental framework for understanding and describing [[nature]] at the infinitesimal level, for the very [[practical]] [[reason]] that it works. It is "in the nature of things", not a more or less [[arbitrary]] [[human]] preference. | As incorporated into the [[theory]] of [[quantum mechanics]], this is regarded by physicists as part of the fundamental framework for understanding and describing [[nature]] at the infinitesimal level, for the very [[practical]] [[reason]] that it works.
