readiness, or tendency, without constraint; as, a

Syn: Voluntary; uncompelled; willing.

Usage: Spontaneous, Voluntary. What is voluntary is the
result of a volition, or act of choice; it therefore
implies some degree of consideration, and may be the
result of mere reason without excited feeling. What is
spontaneous springs wholly from feeling, or a sudden
impulse which admits of no reflection; as, a
spontaneous burst of applause. Hence, the term is also
applied to things inanimate when they are produced
without the determinate purpose or care of man.
``Abstinence which is but voluntary fasting, and . . .
exercise which is but voluntary labor.'' --J. Seed.

Spontaneous joys, where nature has its play, The
soul adopts, and owns their firstborn away.
--Goldsmith.
