Yeoman's Rules of Logic.

Chesterton's Fence:

There exists in such a case a certain institution or law; let us say, for the sake of simplicity, a fence or gate erected across a road. The more modern type of reformer goes gaily up to it and says, “I don’t see the use of this; let us clear it away.” To which the more intelligent type of reformer will do well to answer: “If you don’t see the use of it, I certainly won’t let you clear it away. Go away and think. Then, when you can come back and tell me that you do see the use of it, I may allow you to destroy it."

Chesterton, The Thing. 

Hanlon's Razor

Never attribute to malice that which can be adequately explained by stupidity.

Occam's razor

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

The Red Herring Fallacy

 This is the diversion of a proposition with an unrelated proposition.

For example:

"You think Trump is demented?  Well what about Biden?"

I hear this all the time.

Saying Trump is demented, and I have, doesn't mean that I'm saying Biden doesn't have mental decline.  It means that Trump is demented.

This is to mean that in weighing the scales of two candidates dementia, if one is more demented than the other, that means neither was a good choice, not that one is a hero and the savior of the republic and not demented.

Put another way, choosing to be served a cowpie sandwich, where the alternative was a horseshit sandwich, doesn't mean that cowpie sandwich is are great.  You are still eating shit.

And that means  you need a new menu.

The Two Choices Rule.

If you are presented with "two choices" it doesn't mean there are only two choices, only that the presented is presenting you with two choices.  Accepting the presentation simply because it was presenting that way makes the accepting party the operative figure in there being only two choices.

Yeoman's Gate:

Before you go through a gate to get to the other side of a fence, completely figure out, to the extent you can, where the path goes.

Yeoman's Gatekeeper

If somebody is holding a fence open, urging you to go through, or keeping it closed, trying to bar you from doing so, ask what interest he has in either action.

Yeoman's Self Centered Razor

Something is not true, or false, because that answer fits your deeply held metaphysical or philosophical beliefs.  Nor is something true, or false, because that answer comports with your own self-interest.
