If there is no God, and everything in this world is the product of (as Bertrand Russell famously put it) “an accidental collocation of atoms,” then there is no actual purpose for which we were made–we are accidents. If we are the product of accidental natural forces, then what we call “beauty” is nothing but a neurological hardwired response to particular data. You only find certain scenery to be beautiful because you had ancestors who knew you would find food there and they dsurvived because of that neurological feature and now we have it too. In the same way, though music feels significant, that significance is an illusion. Love too must be seen in this light. If we are the result of blind natural forces, then what we call “love” is simply a biochemical response, inherited from ancestors who survived because this trait helped them survive.
