Atheism is kind of funny. We all naturally tend to believe certain things like being able to know truth, morality--some things really are bad like perhaps the crusades, "we" exist and are responsible for our decisions--even our thinking ability, justice ought to be served and the like. Because of this, I doubt there is an Atheist alive who is not an inconsistent Atheist. For to believe in many of these things, such beliefs have a basis in Theistic foundations that an Atheist must unwittingly borrow from.
So let me get started with some. I know I'm writing to the choir here, but I'm happy for an Atheist or two to try and defend against my statements if moderators allow.
- Atheists often say they accept what can be seen, smelt, touched, heard or tasted (i.e., accept truth about the world via physical senses). Yet, they fail to justify how that truth can be known without embracing fideism.
- Atheists often say that God would be morally wrong to allow pain and suffering in the world if He is all-powerful and all-benevolent (or say "send people to hell"). Yet, the reality of concepts are not physically sensed--including objective moral concepts that some things really are wrong while other things really are bad regardless of what anyone thinks. Such wreaks of Theism.
- Atheists often claim to be free thinkers, while embracing that we're the product of entirely physical processes and could not be other than what we are (Determinism).
- Atheists often claim moral superiority in doing "good" for goodness sake rather than God's sake, yet what is the superior morality of which they speak and how is it they stand above the physical processes that constructed them to be "morally superior"?
- Atheists often adhere to Physicalism, yet then believe what we sense of the world is true of the world. Yet Science, particularly physics, forces us to conclude that the world contains colourless particles and waves. Colour is therefore an illusion, a mental abstraction of the physical world that in fact nowhere exists in the physical world. A tinge of inconsistency here perhaps?
- Atheism is built upon the hypocrisy of beliefs it pretends to have, but ultimately cannot sustain.
