It may technically impossible to represent what cannot be said even to occupy space or exist in time in a particular way, but many artists and scientists continue to try to describe indeterminacy. If an atom had no regular attractions and repulsions, if its mass was at one instant nothing, at another a ton, at another a negative quantity, if its motion instead of being continuous, consisted in a series of leaps from one place to another without passing through any intervening places, and if there were no definite relations between its different positions, velocities and directions of displacement, if it were at one time in one place and at another time in a dozen, such a disjointed plurality of phenomena would not make up any existing thing. Not only substances, but events, too, are constituted by regularities. The flow of time, for example, in itself is a regularity. The original chaos, therefore, where there was no regularity, was in effect a state of mere indeterminacy, in which nothing existed or really happened.
Pure indeterminacy is rather boring.
But Pierce goes on to describe the effects of indeterminate actions over time. That's when things get interesting. As noted above, in any totally random environment, a regularity might suddenly occur, as they do sometimes by chance, such as when someone wins the lottery with numbers that correspond to, say, one's height and weight. In an evolving environment, where each move of the game changes the rules and affects subsequent moves, regularities have a slightly better chance of persisting than not. We can now avoid having to fall back upon conceptions like God, or Spirit or Essence, without succumbing to meaninglessness.
