What We Call Randomness

I'm reading Dan Dennett's book Freedom Evolves. I'm about 120 pages in, and it's absolutely wonderful. Anyone who likes Dennett will like the book, and anyone who's read his other stuff will find it enriching, as it helps to tie the ideas together.

I've considered what it means to be "random." In acknowledging, as I often have (as a determinist, or at least I think I am) that the outcome of a situation is dictated by the conditions leading up to it, I've been forced to reconsider a definition of the term "random." After all, it'd be silly to throw away perfectly good word.

The point, though, is that I think I've found a way to change my understanding of the adjective without changing the nouns that it speaks for.

When we engage in a "random" coin flip, we are not engaging in randomness in that conventional sense, as the result of the coin flip is predetermined by the nature of physics, the forces exerted by the thumb that does the flipping, gravity, air resistance and any number of other things.

What we are actually doing is availing our decision to forces outside of our mind. What we are doing is taking that internal mechanism, that thought process that leads to decisions, and circumventing it by making the decision contingent, not on our past experience or our current inclinations, but on the laws of physics and the forces on a coin.

Randomness becomes an expression of sacrificing control. When you consider this, you may acknowledge that this is already something that you thought about randomness, that this was already the definition.

Random means, literally, an occurrence without aim.

That is what we need to redefine randomness as. Occurrence without intention, not "occurrence without cause," which is the present definition.

Occurrence without cause is not possible. Occurrence without intention makes sense.
