Logical positivists ask: "What is the meaning of life?", "What is the meaning in asking?"[1][2] and "If there are no objective values, then, is life meaningless?"[3] Ludwig Wittgenstein and the logical positivists said:[citation needed] "Expressed in language, the question is meaningless"; because, in life the statement the "meaning of x", usually denotes the consequences of x, or the significance of x, or what is notable about x, etc., thus, when the meaning of life concept equals "x", in the statement the "meaning of x", the statement becomes recursive, and, therefore, nonsensical, or it might refer to the fact that biological life is essential to having a meaning in life.
