In his famous novel Nineteen Eighty-Four George Orwell gave a nice (if for us ironical) explanation of the boon Carnap expects from the logical reform of grammar. Right-thinking Ingsoc party members are as offended as Carnap by the unruliness of language. It's a scandal that grammar allows such pseudo-statements as 'It is the right of the people to alter or abolish Government' (Jefferson), or 'Das Nichts nichtet' (Heidegger). Language as it is makes no objection to such statements, and to Carnap, as to the Party, that's a sore defect. Newspeak, a reformed grammar under development at the Ministry of Truth, will do what Carnap wants philosophical grammar to do.
However, neo-positivism failed dismally to give a faithful account of science, whether natural or social. It failed because it remained anchored to sense-data and to a phenomenalist metaphysics, overrated the power of induction and underrated that of hypothesis, and denounced realism and materialism as metaphysical nonsense. Although it has never been practiced consistently in the advanced natural sciences and has been criticized by many philosophers, notably Popper (1959, 1963), logical positivism remains the tacit philosophy of many scientists.

This initial formulation of the criterion was soon seen to be too strong; it counted as meaningless not only metaphysical statements but also statements that are clearly empirically meaningful, such as that all copper conducts electricity and, indeed, any universally quantified statement of infinite scope, as well as statements that were at the time beyond the reach of experience for technical, and not conceptual, reasons, such as that there are mountains on the back side of the moon.
