Not at all a modern idea. Pico della Mirandola would rank mere being the lowest form of existence, the same sort of existence a plant has.
Mirandola's is the oldest source for the ranking of being that I can recall off the top of my head, but the idea is almost certainly even older.
> On man when he came into life the Father conferred the seeds of all kinds and the germs of every way of life. Whatever seeds each man cultivates will grow to maturity and bear in him their own fruit. If they be vegetative, he will be like a plant. If sensitive, he will become brutish. If rational, he will grow into a heavenly being. If intellectual, he will be an angel and the son of God.
- Oration on the Dignity of Man
It goes even farther back than that, I mean the stoics were preaching things like live each day like it's your last, and there are proverbs from ancient China like "being the rat in the granary than the rat in the toilet". At the same time there are plenty of counter examples and people teaching the opposite, like Diogenes.
I think it's useless trying to find councel regarding these things, people will just say what they believe is right. It's mostly just seeking external validation.
The end state should just be a lack of judgement -- right now we are too preoccupied with minmaxing so called productivity which is mostly an illusion most times. Much of this comes from a self imposed sense of guilt, in that doing nothing becomes like eating junk food. And this sense of guilt is in turn cultivated by the environment at large. Try telling people you're in between jobs or taking a sabbatical, they'll just assign you to the "loser" or "unemployed" class automatically.
Interesting thank you. Mirandola is still modern in my eyes. Btw I really enjoy marginalia. Helped me find Tom Murphy [1], which I’m kind of basing this being modern off of, through the explore page. Crazy full circle moment.
