5. verificationism การตรวจสอบความถูกต้อง
Although it comes in many varieties,
verificationism is characterized by a general
distrust of claims that cannot be shown to be true,
or verified, using only empirical methods like
those available to the natural sciences. Many held
that because the claims of ethics, metaphysics,
and religion cannot be empirically verified, they
are meaningless. Although this view of meaning
is largely discredited today, it was highly influential
in the early twentieth century.
