"The common behavior of mankind is the system of reference by means of which we interpret an unknown language"
About this Quote
The intent is almost diagnostic. Wittgenstein is treating misunderstanding as a philosophical illness caused by thinking language is primarily a code. The subtext: if you’re lost, the problem may not be vocabulary but the “form of life” you’re trying to enter. That phrase matters because it pushes against a seductive picture of communication as private, inner translation. If language were truly private, no “system of reference” could exist; there would be nothing stable to check your interpretation against except your own impressions.
Contextually, this belongs to Wittgenstein’s break from his earlier, more formal view of language (the Tractatus era) toward the Investigations, where rules are not abstract rails but practices people learn by participation. It’s also a sly warning to philosophers: stop inventing metaphysical meanings and start observing ordinary cases. The irony is that “mankind” here isn’t romantic; it’s methodological. The messy, repetitive, unglamorous regularities of human life are what make understanding possible at all.

Evidence: The common behaviour of mankind is the system of reference by means of which we interpret an unknown language. (Part I, §206). This sentence is from §206 of Wittgenstein’s posthumously published book Philosophical Investigations (original German title: Philosophische Untersuchungen). The Ludwig Wittgenstein Project hosts a public-domain reproduction of the German text; in that German original at §206 it reads: “Die gemeinsame menschliche Handlungsweise ist das Bezugssystem, mittels dessen wir uns eine fremde Sprache deuten.” The standard English translation is by G. E. M. Anscombe; the quote is commonly cited as PI §206 (Part I). The *first publication* of this remark as part of Wittgenstein’s own work is the 1953 first edition of Philosophical Investigations, published after his death (1951).
