Is there an external reality? By Manuel Lozano Leyva

This post is also available in: Spanish

That’s the eternal dilemma between materialism and idealism. In Physics, at the quantum level, it has been shown that measurements alter reality, what we’re measuring, and out of purely physical reasons, not philosophical ones, so there’s still no reason to say we’ve solved that problem. An electron may be there or may just be generated by the interaction with our measurement. That’s the eternal question: is the moon there if we’re not looking at it? We can’t be sure. But the answer is yes, it’s there. But, at the quantum level, at the atomic scale, things start to get complex. So Physics cannot elucidate between Platonism and materialism; whether there’s an external reality or not. That belongs to the realm of each person’s philosophical attitude.
