What makes a good thought?

I would say an idea is a special kind of thought that is an interesting thing. It’s maybe a little more than a thought, but still a thought. I don’t know if there are good and bad thoughts tough. Don’t know when something becomes good or bad. Is it only actions that can be good or bad or can thoughts also be defined that way? I don’t know.
So eh, I don’t know what a good thought is.

I don’t think I know the answer to your question. Sometimes a good idea just pops up. Sometimes you have to think about it and move from thought to thought before it becomes good. Good and bad are judgmental and subjective; different from person to person. One person’s good thought may another’s eh, or no way! And then there’s the idle thought that comes and goes like a butterfly. It just is.

The best thought ( or solution) is profound in its simplicity. Hard to get much simpler than Descartes.

DesCartes was asked whether he wanted fries with his hamburger.  “I think not,” he said, and instantly vanished.

I would never use “minimum acceptability” to describe a good thought, and, come to think of it, I am not even sure what a good thought is.

Are you talking about an aphorism or a maxim or a pithy saying?

Good is a normative evaluation; a judgment. What makes a thought good? Someone has to decide it is good. It’s as simple as that.

There is no objective answer to this question because good and bad are human determinations. Without humans around, there is no good and bad. There is noone to make the determination.

No idea. All I know is that when I look at something and then it explodes to bits and pieces, then that’s good.

A thought is neither good nor bad until you start thinking about it.
