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

Most Powerful Occam's Razor quotations

Entia non sunt multiplicanda praeter necessitatem

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.

With all things being equal, the simplest explanation tends to be the right one.

It is vain to do with more what can be done with less.

Nonbeing must in some sense be, otherwise what is it that there is not? This tangled doctrine might be nicknamed Plato's beard; historically it has proved tough, frequently dulling the edge of Occam's razor.

Of two equivalent theories or explanations, all other things being equal, the simpler one is to be preferred.

While Occam's razor is a useful tool in the physical sciences, it can be a very dangerous implement in biology. It is thus very rash to use simplicity and elegance as a guide in biological research.

So Occam's razor - Occam says you should choose the explanation that is most simple and straightforward - leads me more to believe in God than in the multiverse, which seems quite a stretch of the imagination.

Scientists often talk of parsimony (as in "the simplest explanation is probably correct," also known as Occam's razor), but we should not get seduced by the apparent elegance of argument from parsimony; this line of reasoning has failed in the past at least as many times as it has succeeded.

Nature operates in the shortest way possible.

People don't want to know the truth.

Were it not for Occam's Razor, which always demands simplicity, I'd be tempted to believe that human beings are more influenced by distant causes than immediate ones. This would especially be true of overeducated people, who are capable of thinking past the immediate, of becoming obsessed by the remote. It's the old stuff, the conflicts we've never come to terms with, that sneaks up on us, half forgotten, insisting upon action.

Therefore to the same natural effects we must, as far as possible, assign the same causes.

If a thing can be done adequately by means of one, it is superfluous to do it by means of several; for we observe that nature does not employ two instruments [if] one suffices.

Occam's razor suggests that, if some event is physically plausible, we don't need recourse to more extraordinary claims for its being. Surely the requirement of an all-powerful deity who somehow exists outside of our universe, or multiverse, while at the same time governing what goes on inside it, is one such claim. It should thus be a claim of last, rather than first, resort.

Entities are not to be multiplied beyond necessity.

And this shows that sometimes people want to be stupid and they do not want to know the truth.
