We were having some sort of discussion where the idea of a "moral agent" came up, and Lily asked what one was. I described the idea, including something along the lines of "if it hurts you is that it's fault?", and then asked her what counted. Her answers, with my ordering:

• Rock: no
• Ocean: no
• Tree: no
• Ants: no
• Pigs: no
• Monkeys: no
• Babies: sort of
• Morgan (9m cousin): sort of
• Felix (18m cousin): in between
• Oli (3y cousin): yes
• Anna (4y sister): yes
• Ruthie: yes
• Fairies: yes
• Anna pretending to be a baby: yes

I'm curious whether adults would give the same answers, or whether adults would typically consider moral agency to start later?
