> Fully human being is very hard to explain. According to my knowledge of Huxley is that it's someone who has essentially reached an ego state that has certain values(life, beauty, suffering). All is each which is all.

Defining fully human as being in the nihilistic ego-destroyed state where differentiation between the Self and all existence is nullified is another fictional ideal. Huxley himself borrowed from eastern philosophy of Vedanta, of which Huxley was a student.

It's a deeply interesting path of thought to go down as an individual, but it shouldn't be mistaken as a prescription for how to be fully human in society a practical way, or a principle around which to configure society.

I would argue that when Huxley said that realising all is each is all he didn't intend you to lose your ego. In my opinion he intended you to realise that there is power in the self and that everyone has a self and therefore there is a universal ego that we would call humanity.

But I suppose every proverb is a platitude..

To be human is to have a brain, and the brain exists to do technology and social organization. Separating the two is absurd... the human animal, left on its own devices, naturally creates technology and societies, so all these things are just as natural.

To be human is to have something an incredible number of other species have?
