An important idea in this work is that of "ostensive definition", when an object is pointed out as the meaning of a word. Concepts advanced in this work include family resemblance, and the private language argument. The author quotes Plato's Theaetetus as an example of the idea that names signify "simples." In the first sections, the author considers complexes of words like "five red apples," repudiating the picture theory. He also introduces the term "form of life" to describe language use. Beginning with a quote from St. Augustine, the author uses this quote to advance the idea that language is a game. FTP, identify this work by Ludwig Wittgenstein which disproves the ideas in his earlier Tractatus Logico –Philosophicus.
