 When the book was published in 1928, it was widely discussed and, along with Wittgenstein’s Tractatus, became one of the classic texts of the Vienna Circle. Its effect was amplified in the English-speaking world by A.J. Ayer’s endorsement of it in his best-selling Language, Truth, and Logic (Ayer 1936), which however misrepresented the book quite seriously. This misrepresentation contributed to the neglect of the book among Anglo-American philosophers, which even the sophisticated discussion, critique, and further development by Nelson Goodman (1951) or the belated English translation (1967) could not affect. It also allowed many preconceptions about the book to continue circulating almost through the end of the twentieth century.
