This material consists of the text of eight lectures given in London in 1918.
The subject matter is mainly the relationship between language and reality, culminating with a metaphysical view "on what there is".
The ideas about language derive from the advances in mathematical logic on which Principia Mathematica is founded, and assume that these advances provide an insight into the structure of ideal languages in terms of which a correct analysis of the meaning of ordinary language must be based.
The relationship between language and reality is based on but not the same as ideas of Wittgenstein later published in his Tractatus Logico-Philosophicus.
