Document Summary

Simple concepts are the building blocks of where are our knowledge is created and functioned. Wittgenstein proposed that members of a category have family resemblance to one another. Features a family has but identity of those common features depend o(cid:374) (cid:449)hat su(cid:271)group of the fa(cid:373)ily you"re (cid:272)o(cid:374)sideri(cid:374)g. If a test (cid:272)ase has (cid:272)ertai(cid:374) attri(cid:271)utes the(cid:374) it"s i(cid:374)side the (cid:271)ou(cid:374)daries. If a test (cid:272)ase does(cid:374)"t ha(cid:448)e defi(cid:374)i(cid:374)g attri(cid:271)utes the(cid:374) it"s outside the (cid:272)ategory. Best way to identify a category is to identify its centre rather than its boundaries. Use the ideal as the anchor for conceptual knowledge, your reasoning is done with reference to the prototype. Me(cid:373)(cid:271)ership is a (cid:272)ategory depe(cid:374)ds o(cid:374) rese(cid:373)(cid:271)la(cid:374)(cid:272)e to prototype a(cid:374)d it"s a (cid:373)atter of degree. Standard is the prototype (represent an entire category) Graded membership: objects closer to prototype are better members of category than objects farther from prototype. Certain types of (cid:272)ategories are pri(cid:448)ileged i(cid:374) their stru(cid:272)ture a(cid:374)d the (cid:449)ay they"re used.
