Figure out what's true if you can.

If you can't, then figure out if you should believe an authority.

If you figure out that you should believe an authority, then figure out which authority you should believe.

If you can't, then figure out which authority you should probably believe.

If the authority you believe tells you that you've figured out something wrong, then go back and figure it out again.

If you figure out that you don't have enough data to figure it out, then continue to believe your authority.

If you figure out that you do have enough data to trust what you've figured out, then figure out that you should quit believing that authority, and go believe whatever authority looks most believable.

And do what your authority tells you to do, because if you don't, then you may never acquire enough data to figure out if you should keep on believing that authority.

If you do what your authority tells you to do, and you don't get the results your authority said you would get, then that data should cause you to figure out that you should quit believing that authority.

If your authority tells you that you shouldn't figure this out, and you choose to believe your authority anyway, then you do so because you fear your authority more than you want to know truth - which is stupid.  Even if your authority tells you he will torture you forever for not believing him, your Creator, who designed you to figure this stuff out, will let you remain in one of the many assylums for stupid believers of wrong authorities, until you figure out that you don't belong there.
