Moral Realism: G. E. Moore

Moral realism is the philosophical view that moral facts exist independently of our beliefs or feelings. According to moral realists, statements like "murder is wrong" can be true or false based on objective moral truths, much like scientific facts. G. E. Moore, a key figure in moral philosophy, argued against simple definitions of good, famously using his "open question" argument to show that knowing the meaning of "good" doesn't reveal its nature. This highlights a distinction between moral realism and anti-realism, the latter denying objective moral truths and suggesting that moral values are shaped by individual or cultural perspectives.
