{{Main|Principle of sufficient reason}}
The principle states that every event has a rational explanation.<ref>[https://plato.stanford.edu/entries/sufficient-reason/ "Principle of Sufficient Reason."] {{Webarchive|url=https://web.archive.org/web/20180611143503/https://plato.stanford.edu/entries/sufficient-reason/ |date=2018-06-11 }} ''Stanford Encyclopedia of Philosophy''. 7 September 2016. 25 October 2017.</ref> The principle has a variety of expressions, all of which are perhaps best summarized by the following:

:For every entity ''x'', if ''x'' exists, then there is a sufficient explanation for why ''x'' exists.
:For every event ''e'', if ''e'' occurs, then there is a sufficient explanation for why ''e'' occurs.
:For every proposition ''p'', if ''p'' is true, then there is a sufficient explanation for why ''p'' is true.

However, one realizes that in every sentence there is a direct relation between the predicate and the subject. To say that "the Earth is round", corresponds to a direct relation between the subject and the predicate.
