§65

We might imagine an objection which is something along the lines of - you're good at criticising my account of the essence of language but it's much easier to criticise than to offer a positive account of your own. Where's your account of the essence of language?

Wittgenstein's response is to say that to think that there is something essential - common to all language-games - or to think that there must be something common to all language-games (in virtue of which they count as language-games) is mistaken and misleading.

Language-games do not have a single feature in common but there are various similarities between language-games. - Much like games (§66).
