Simpler explanations are, other things being equal, generally better than more complex ones.

No more things should be presumed to exist than are absolutely necessary.

The explanation requiring the fewest assumptions is most likely to be correct.

Pluralitas non est ponenda sine necessitate. A plurality (of reasons) should not be posited without necessity.

For nothing ought to be posited without a reason given, unless it is self-evident (literally, known through itself) or known by experience or proved by the authority of Sacred Scripture.

God's existence cannot be deduced by reason alone.

My God is the green tide in the spring leaves the redness of cherries high in the air the excitement of shooting stars the song of birds in summer branches the sunrise on a winter's morning the name of everything we don't understand.
