In my view, the history of humanity is filled with individuals who have proposed systems from which morality, or what is good, is defined.
Such systems range from a person claiming to be the moral compass of humanity, and that he/she is just perfectly right. Hence proposing that we should basically copy him/her to be maximally moral/good.
Another example is Kant, who proposed the categorical imperative by which the moral compass is within each individual. E.g. it is moral if I do X as long as I'm fine if others do X to me.
I am sure that there are many more philosophers that have attempted to improve upon these definitions of morality/good, or even proposing some definition that is totally different, and better.
But my problem is that I don't know where is today's state of philosophy on "morality/good". E.g. are philosophers mainly still following Kant's view as the most plausible one?
Hence my question is: generally, what is the most accepted definition of morality/good in philosophy, today?
