The speaker argues that current scientific progress in areas like quantum mechanics and cosmology necessitates a return to natural philosophy.

“we're at a point in physics right now where questions like you know what is an observer what is infinity why is the past different from the future what is emergence like these are physics questions but it clearly was different from all other nights”

Scientific theories should be evaluated based on their mathematical progress, even when experimental testing is currently unavailable.

“if you are like me and many of my colleagues willing to defer observation and experiment for now not forever but defer it now develop the mathematics in the hope that this risk that we are taking that this math may not be relevant to the world but if it is it will give us the deepest explanation of ”
