Razor #4: Hume’s Razor

Hume’s Razor:

If the cause, assigned for any effect,
be not sufficient to produce it,
we must either reject that cause,
or add to it such qualities as will
give it a just proportion to the effect.

Thought:

A cause that is inadequate
to explain an effect
is not the cause,
or not the only cause,
or just a supporting condition.

(In philosophy, a razor is a principle or rule of thumb that allows one to eliminate (‘shave off’) unlikely explanations for a phenomenon, or avoid unnecessary actions.)
