As we observed in the last post, John Locke attempted to update Aristotle's view of universals by saying that we select key attributes for defining categories based upon our objectives. So, we can look at games, decide what salient features they all have in common and define the concept of game based upon those features. It looks like the project might be gaining altitude again. But, instead it will take a nosedive.
David Hume would observe that we form categories based on a subconscious cognitive process that cannot be made explicit. That is, we go about our business in the world, experience games, and form a visceral concept of what a game is. Any attempt to explicitly define characteristics would be artificial and doomed to failure. The Supreme court justice who admitted that he could not define pornography but claimed - "I know it when I see it", was embodying Hume's view of universals.
If Hume steered the project into a nose dive, Wittgenstein let it crash and burn. According to him, the only thing the elements of some categories have in common is that they are members of the same category. He used a, now famous, analogy to family resemblances. If you go to a family reunion and look at the members of the family you will see common elements. Some will have the family eyes. Some will have the family nose or mouth. Some the family brow. And so on. There are overlapping features held by subsets of the family but no set of features common to all. For example, not everyone has the nose. Or not everyone has eyes. Universals, according to Wittgenstein, are made the same way. You cannot define a core set of attributes because there is no core set of attributes that all instances have in common. And the concept he used to illustrate this was - you guessed it - games!
Should we despair at this point and give up our attempt to define what constitutes a game? Should we despair that if this is true knowledge is not really possible? No, that would be a little overly dramatic. Instead we will back up and see where these great minds went wrong. We will go back to some road signs provided by Bacon and Aristotle and try to get back on the right path. And that will be the topic of the next post.

Whether or not categories are simply a form of ordering imposed by men as a convention or whether they exist apart from this ordering in some way that allows them the dignity of being nouns, they are nevertheless useful in activities such as sorting out your sock drawer.
