I suspect everyone who knows atheists has encountered people who say that atheism does not entail nihilism, because “life has the meaning you give it”. I just want to mention a small point regarding that.
My favorite definition (more a description) of “reality” is:
That which, when you stop believing it, doesn’t go away.
It’s not a complete description, but it’s a pretty good working description, especially in our confused times. Anyway, it’s worth noting that “the meaning you give to life” goes away when you stop believing in it.
The atheist retort that atheism does not entail nihilism thus amounts to:
Life doesn’t have any meaning, but I can pretend that it does.
Which no fool ever doubted.
