The Dawn of a Mindful Universe: A Pathway towards a Biocentric Global Ethics

This article presents arguments for a biocentric worldview based on the rarity and uniqueness of planet Earth as confronted with trillions of other worlds in our galaxy alone. This cosmic outlook comes from recent astronomical knowledge concerning the distribution of exoplanets and the growing understanding of the interconnectedness and codependence of all life on Earth, past and present. Confronting the uniqueness of Earth’s biosphere and its current fragile state due to centuries of aggressive human presence, the biocentric worldview proposes an ethics of belonging that takes life center stage as humanity struggles to chart its path toward a sustainable future.

Reality Is Not a Simulation and Why It Matters

The idea that we are living in a simulation has become commonplace. Elon Musk, for example, thinks it is almost certain we are living in a simulation. But the simulation hypothesis comes up against insurmountable problems, and is, in the end, an excuse for us not to sort out our real moral failings, writes Marcelo.

There’s So Much That Science Will Never Be Able to Explain

If there is a final truth out there, it’s beyond us. Science works under strict boundaries, and as hard as we may try, we can’t go beyond them. To know all answers, we need to start by knowing all questions. And that is simply impossible. Our view of the world will always be incomplete.
