Exactly. Good philosophers are careful with definitions. Do you think there's enough space on your one page to define your terms and reach a conclusion that would satisfy most reasonable people?

Well, I wouldn't include ethics at all, I think it falls under biology, psychology, sociology.

The core of philosophy is basically understanding consciousnes, not too much else to it. But I guess one page was an exaggeration, let's say five.

Those sciences don't touch upon what ethics is about, which is what is good and bad, right and wrong.

There is no "core of philosophy", and it's certainly not confined to "understanding consciousness". I'd have to agree with others here who have tried to admonish you that you're arguing from ignorance and being unserious, even if a great deal of what passes for philosophy is a waste of time. What about logic, philosophy of mathematics, philosophy of language, ...?

True, but this is where ethics logcally belongs to. It's just an aspect of human behavior and inner world.

Asking what is good or bad is like asking what is the definition of these words. Well, the definition is whatever we agree on. IMost people call "bad" the behavior, that triggers specific emotion of "wrongness".

I think that consciousness and closely related topics is the hard part, other things such as ethics or aesthetics have quite mundane explanations. Philosophy of mathematics nad language is somewhere in between.
