Constructs named for this concept were first demonstrated with an example where pillars, slabs, and beams are passed between a builder and his assistant. A focus on everyday instances of this concept characterizes an “ordinary” philosophical method followed by J. L. Austin. Gottlob Frege (“FRAY-guh”) is often credited with starting the “turn” towards this concept that began analytic philosophy. (10[1])The “beetle (10[1])in the box” thought experiment was used to argue that private examples (10[1])of this concept (10[3])cannot exist by Ludwig Wittgenstein. A field that studies these systems has branches like pragmatics and semantics. For 10 (10[1])points, name these systems studied in linguistics. (10[1])■END■
