. We speak of a thing as accidental when
it falls out as by chance, and not in the regular
course of things; as, an accidental meeting, an
accidental advantage, etc. We call a thing incidental
when it falls, as it were, into some regular course of
things, but is secondary, and forms no essential part
thereof; as, an incremental remark, an incidental
evil, an incidental benefit. We speak of a thing as
casual, when it falls out or happens, as it were, by
mere chance, without being prearranged or
premeditated; as, a casual remark or encounter; a
casual observer. An idea of the unimportant is
attached to what is casual. Fortuitous is applied to
what occurs without any known cause, and in opposition
to what has been foreseen; as, a fortuitous concourse
of atoms. We call a thing contingent when it is such
that, considered in itself, it may or may not happen,
but is dependent for its existence on something else;
as, the time of my coming will be contingent on
intelligence yet to be received.
