Freddie is right about one thing: once we eliminate necessity, we need reasons to think that our minds are of the right sort; after all, the humble Giraffe is well adapted to its environment, but will never come to understand particle physics or the workings of its own neurophysiology. How are we to know that we are not like Giraffes, only with considerably wider possible-knowledge horizons? A simple response is that we haven’t failed yet. The theories we build in order to explain the universe around us are remarkably, even distressingly successful.
