There is another very similar form of argument,
which consists in the inference of facts from their
efficient causes or the reverse, a process known as
argument from causes. The conclusion is sometimes
necessary, sometimes generally without being necessarily true. For instance, a body casts a shadow in
the light, and the shadow wherever it falls indicates
the presence of a body.
