Could our universe be infinitely big? Could it be infinitely old? Could there be infinitely many separate universes? Although arguments against the existence of such physical infinities have been made throughout history, it is only in recent years that substantial arguments against their existence have been made. This article adds to the case against physical infinities and lists some of the astounding implications if no types of physical infinities exist.

According to the extended mind hypothesis, the mind can extend into the physical world via tools, devices and systems external to the brain. This article explains the hypothesis and explores its implications for knowledge, identity, education and digital ethics. It also highlights a deeper concern: if the mind is extended, then it is also fragile. This fragility stems from its dependence on infrastructure, institutions and systems that we often don’t control.

The evil-god challenge brings to scrutiny a belief taken for granted by many traditional theists: God’s goodness. Evil-god challengers claim that evil-god parodies of theistic arguments are as reasonable as the originals, calling into question the assumption of God’s goodness. I take a new approach to this challenge by considering how great good and great evil are best promoted in conjunction with evil-god’s character and evidential arguments regarding lost or absent goods and evils. I conclude that the world has lost far too many great evils for the evil-god hypothesis to be a serious challenge to traditional theistic belief in God’s perfect goodness.
