In logic, a universal negative is a proposition of the form “No S is P.” Symbol: E, e.[1]
An example of a valid universal negative is "No triangles have four sides". This is a valid universal negative because if something does not have three sides, it cannot be a triangle.
Contrary to the false assertions of logic/philosophy neophytes about it being impossible to prove a universal negative, some universal negatives can be proven.[2] However, atheists universal negative claim that God does not exist is not a reasonable claim.
