Is Logic Possible?

This is more a set of comments than a post. In a sense it is also a spoiler alert for a future post.

The question is: Is logic possible?

We know some things. Like 2 + 2 = 4. I don't mean just that one sum. I mean arithmetic itself. And also things like triangles, circles, lines, and colors, and the sizes of things. Like that.

[Some people are not sure we know things like colors in the same way as numbers because we each see colors differently, so if you are thinking along those lines now, then substitute the idea of colors in place of any specific colors.]

Okay. Now coming at the problem from another direction, there is an old boy scout song that goes something like this (I've used this before elsewhere):

Great green globs of greasy grimy gopher guts,
Mutilated monkey meat,
Itty bitty birdy feet,
French-fried eyeballs floating in a pool of pus,
And me without a spoon.

What do we make of that?  Is it something we know something about, like arithmetic? I know it is a silly song, but no sillier than the story of Rat, Mole and Toad. I could just as well have used this from Dylan:

Grandpa died last week
And now he's buried in the rocks
But everybody talks about
How badly they were shocked
But me, I expected it to happen
I knew he'd lost control
When he built a fire on Main Street
And shot it full of holes
Oh, Mama, can this really be the end
To be stuck inside of Mobile
With the Memphis blues again

Here's the point. I think of all songs and stories as conveyances, and as art. And therefore I come to think of life as a conveyance, and as art.

Coming back to Logic, I found one definition that renders it to mean "a science that deals with the principles and criteria of validity of inference and demonstration ..."

Another renders it as "reason or sound judgment, as in utterances or actions."

So, I wonder, is logic possible? And if so, does it take us anywhere?
