Quantum gravity (QG) is the field of theoretical physics attempting to unify quantum mechanics with general relativity in a self-consistent manner, or more precisely, to formulate a self-consistent theory which reduces to ordinary quantum mechanics in the limit of weak gravity (potentials much less than c) and which reduces to Einsteinian general relativity in the limit of large actions (action much larger than reduced Planck's constant). The the...

Problem of evil
In the philosophy of religion and theology, the problem of evil is the question of whether evil exists and, if so, why.

Brain in a vat

The paradox identifies apparent inconsistency between three seemingly true beliefs about population ethics. The paradox arises from consideration of four different... -

It refers to a hypothetical situation wherein an ass, placed precisely midway between a stack of hay and pail of water, will die of both hunger and thirst since it cannot make any rational decision to choose... -
Argument from poor design
The dysteleological argument or argument from poor design is an argument against the existence of God, specifically against the existence of a creator God (in the sense of a God that directly created all species of life). It is based on the following chain of reasoning: The argument is structured...
