Me in 2017 was wrapping my brain around Pete Singer.
I don’t remember what opinion Pete Singer had that was just incorrect, despite lengthy justification of it and it took a while to puzzle it out but I figured it out. It had to do with how purely fact finding measures are simply not the right kind of thing to handle value questions ,which are meta.
I figured out that Pete Singer’s value was monetary value.
“Yes because there are meta questions (the values) not answerable by the scientific methods or other fact finding measures.
There have been some attempts to bridge the gap, often to odd extremes. Example: the utilitarianism of Peter Singer uses monetary value or broader economic style utility for ethics. [greatest good for greatest # kind of thing).”
