You know how science is constantly changing? How one theory thats considered correct today will be considered incorrect ten years from now?

Thats the basis for the Theory of Theories.

The premise is this, the Science of the future will be very different from the Science that exists nowadays. So what are we to do? Use incorrect theories because we have nothing better to go on?

These are the questions we must ask ourselves.

So in knowing that down the road what we know now as "true" will be replaced by something different. Do we search for fundamental unmovable truths? Or accept the constant change within science and help to bring about more change?

go with the latter. Change in theories is inevitable, and though science is progressive, paradigm shifts can affect its foundations. All of this compels the adoption of pragmatic notions of truth.

Blend the two together.
