METAPHYSICS: WE SENSE THE WORLD FINE. WE FILL IN THE BLANKS LESS SO
—“Curt, how do you deal with the âwe canât trust our senses so we have no idea what reality consists ofâ argument? I.e. how can we determine if sensory information is false?”—
There is no evidence that we can’t trust our senses at human scale.
So we perceive the world as it exists but at the scale and velocity of our perception.
We have to defend against our cognitive biases that evolved at human scale . Or more simply, we SENSE the world just fine. We often PERCEIVE the world with error.
We improve our perception with more information. we improve it further with falsification (tests of our cognitive biases). And we use instrumentation to EXTEND those perceptions.
So it’s not true that we sense the world incorrectly. We appear to sense it (at human scale) quite accurately, and we tend to perceive it (at human scale) fairly accurately.
But we ‘fill in the blanks’ with lots of error.
So we have to make sure we aren’t filling in the blanks with error.
