Long day; short post. Quite likely my shortest post ever.
Does everything and everyone have to have a “purpose” in life? ‘Twould seem so, according to the Bible. However, “purpose” is an anthropocentric point of view: everything is made for the use of people, including other people.
Sometimes the benefits (not “uses”, but benefits) of having different people around are not obvious. Those odd people don’t fit the neat cogs of traditional social machinery, and society has had to invent new mechanisms to “deal with” the misfits and to isolate them from the social workings.
Thus for example, we get “special education” programs to make up for the fact that the current educational system doesn’t work all that well. Being a heretic, I don’t believe that an educational system that enables students to learn should have to be “special”. (I also don’t believe in the segregation.)
What is really needed is the understanding that it is not the people, but the social machinery which is lacking something that creates this mis-fitting, and therefore, the misfit.
In the way that travel enables us to understand what our home geography and culture is like (by way of comparison and contrast to that which is so familiar as to be unseen), the misfit enables society to learn more. This happens indirectly by illustrating how the social machinery is lacking. Furthermore, the social machinery is often lacking for a lot of people, not just those for whom it’s such a poor fit as to be outright unusable.
This informing also happens directly by the communications we get from all the misfits. Of course, it’s not true communication unless there are those willing to listen, and to take the messages seriously.
People do not have to be equivalent to be equal in their inherent value.
