Metaphysical Subjectivism vs. Objectivism

The problem with subjectivity as an all encompasing philosophy is that we have devices and mechanisms that allow us to observe objective truth. Take the apple, for example. Your eyes might show you blue for what I see as red, but it's still just an expression of the objective truth that light with a wavelength of 680 nm is bouncing off the apple.

But then, there's a problem with an all encompasing objective philosophy - namely that proof of a negative is impossible. So, everything that we cannot prove is potentially subjective. For example, you would have to get every living human being to look at the light analyzing device and verify that it was reporting light in the 680 nm range to prove that it can't be something else to someone. It's a crude example, but you get the point.

So anyway, this boils down to: some things are subjective and some are objective. But you probably knew that already. The trick is not to assume you know which is which intuitively.

Jam it back in, in the dark.
