how does atheism/materialism account for

159. If all the world is a delusion, then there's no point in ANY discussion

As for knowing what is in the mind/brain/subjectivity of others? In human society, intersubjective agreement. Empathy. Assumption that others are like us; while we know our own feelings.

In philosophy, one can philosophically reject the possibility of all objectivity. As say, Post Structuralism seemed to. But eventually even Post Structuralism was philosophically discredited, or bypassed. Most today agree that we can know a reasonably "real" reality. And in any case, in everyday life, most people act as if reality is real: they move out of the way of what appears to be an oncoming bus, acting as if it was real.

Science cannot prove the reality we see is real; but it seems a workable assumption. One that if you abandon, appears to be physically fatal. Science overall accepts the reality of reality therefore.

So given these methodological conventions of Science: can we reasonably discover what is going on in the mind of animals? Given their evolutionary genetic kinship to humans, similarities in brain structure, and occasionally observed similarities in behavior, it seems plausible to many that many of the basic emotions thought to be partially constitutive of religion - like "love" ("God is love," etc.) - are quite likely found in animals.

And the Bible makes parts of this explicit it seems, for Christians: "observe the ravens" Jesus tells us; what they do forms moral lessons - religion. For Jesus at least.
