 A more apt analogy to organized social activity might be an assortment of games that can be played by different combinations of people in different ways. Some games could be played by everyone; others could be modified to include cognitively impaired people in a way that preserved the interest of non-disabled players; some would be beyond the reach of people with certain cognitive impairments. But even the most cognitively gifted individuals could not participate in all games—the sheer amount of training and practice required to master some of them, and the considerable time and energy many of them require, would preclude participation in many or most. Indeed, society may function better if people have varying aptitudes for, and interests in, different activities. (A similar criticism of the card-game analogy is offered by Wong (2007), who recounts how her brother with Down enriched rather than impoverished family life.) The fact that a smaller set of activities may be available to people with cognitive impairments need not present a problem, if it does not result in their social isolation or deny them intellectual challenges (Parens &amp; Asch 2000: 25–26 [quoting Philip Ferguson, personal correspondence]). But ensuring their participation may require society to refashion itself in significant ways.
