An English word name essentially meaning “valid reasoning.” A logical choice to name your child (heh heh), but let’s hope your little Logic is never able to outwit you. At least not during his childhood.
Anything less than Logic would be ... illogical.
Famous people named Logic:
Rapper Logic (real name: Sir Robert Bryson Hall II).
Your little Logic could actually grow up and become a professional logician: i.e., someone whose specialty and area of scholarly study is in logic.
