Yini uWittgenstein ayibheka njengenkinga ekufundeni ulimi esebenzisa "ukuchaza okubonakalayo"?
Context:UWittgenstein ucacisa inkinga yokuxhumana esebenzisa ulimi lomuntu lapho ekhuluma ngokufunda ulimi "ngokuchaza okubonakalayo". Ngokwesibonelo, uma umuntu efuna ukufundisa othile ukuthi ipensela lalibizwa ngokuthi "ipensela" abese ekhomba ipensela athi, "ipensela", umlaleli angazi kanjani ukuthi lokho umuntu azama ukukusho ukuthi into engaphambi kwami (isib., ipensela lonke) ibizwa ngokuthi "ipensela"? Akunakwenzeka yini ukuba umuntu olalele ahlanganise igama elithi "ipeni" nelithi "ukhuni"? Mhlawumbe umuntu olalele wayeyohlobanisa igama elithi "ipensela" nelithi "isiyingi" esikhundleni salokho (njengoba amapensela ngokuvamile eyizindilinga!). UWittgenstein ubhala "ngezincazelo" eziningana ezingase ziphakame ngemva kwesifundo esinjalo. Umfundi angase acabangele ukukhomba kwakho ipensela nokuthi "ipensela" kusho lokhu okulandelayo: (1) Lena ipensela; (2) Lena iyindilinga; (3) Lena ukhuni; (4) Lena iyodwa; (5) Lena iqinile, njll, njll.
Njengesibonelo se- "Ostensive defining" ukhomba into bese usho igama layo. UWittgenstein ubona "ukuchaza okucacile" njengenkinga yokuxhumana ngoba ukuxhumanisa nje igama nento kuletha ukungaqondakali. Ngokwesibonelo, uma othile ekhomba ipensela bese ethi, "pensela", umuntu olalele angase angazi ukuthi lelo gama lisho ukuthini ngempela. Lingasho ipensela ngokwayo, ukuma kwepensela, into eyenziwe ngayo, ubuningi bepensela, noma enye imfanelo yepensela.
