An important collection of articles by the Cambridge analytical philosopher G.E. Moore, published in the same year and in the same book series as Wittgenstein’s Tractatus Logico-Philosophicus.
The books published in the series were generally bound up as demand required, hence later issues of the first editions are often encountered with substantially later advertisement’s bound at the rear. Although the present example contains no such advertisements bound with the text, the printed advertisements on the rear panel of the dust jacket include works published up until 1927, indicating a later issue.
