He rolled his eyes at me. “How sad that you need approval from some external deity. I am happy with my life as it is. I make meaning for my own life, thank you very much. I need approval from no mythological deity.”
I nodded. “Well – I’m glad you are happy with your life. I’m also happy with mine – so that makes two of us! But the issue here isn’t how we FEEL about our lives. Rather, the question is how we make sense of our lives. You say there is no meaning beyond the natural world. We are physical beings and nothing more. Is that what you are saying?
“Yes,” he announced.
“Well,” I continued, “I’m sorry but – there’s a problem with your statement. The problem has nothing to do with whether or not we are open to receiving approval from God or anyone else. Rather – the problem is about the assumptions you are making around the truth and the importance of your words.”
He raised his hand and replied abruptly. “Enough of your talk about God and absolute meaning. I am happy with subjective meaning…I give my own life its purpose. This is important…everyone needs to grow up and do this, particularly religious people.”
I laughed. “Okay. I hear that you think this is important. My question to you is why? Why is it important? And to whom?”
He stopped, a quizzical expression on his face.
I pressed on.
“I hear from many people that we are just physical beings in a physical universe. Neil deGrasse Tyson announces that we are star dust, and we should be happy about that. If all we are is physical stuff…then Neil’s words are meaningless. And – so are yours.”
“Why?” he retorted? Perhaps because Neil says them after Carl Sagan before him, my friend thinks that gives them more meaning. But – if Neil and Carl Sagan are right, their words have no meaning.
I continued. “Because what you are saying is – we are ONLY brains, constructed of biochemistry, composed of atoms that were cooked in the stars. There is no human soul. No God. Right? In that case, I don’t see why the words and thoughts of any of our minds are any more significant than other natural events…like the sound of the wind blowing in the trees.”
Do you see the point I am making to my friend?
1 – if all we are is physical, then everything we do and say and think is ultimately physical.
2 – if everything we do is simply physical, then nothing we do is any more significant than other physical effects in the world. Trees swaying in the wind, for example.
Conclusion: we might think we are profoundly creating our own subjective, personal purpose for our lives. We may write and produce a TV series like Cosmos, even. But actually nothing we do or say or believe actually matters. It’s not true or false, profound or pedestrian. It simply is. We simply are. Like swaying tree branches.
If that is the case – then what we say to each other does not matter, and has no consequence when it comes to truth or significance.
What does this mean? Well, my friend is kidding himself about subjective meaning for his life. He doesn’t even manage subjective meaning for his thoughts!
YET – if there IS objective meaning and purpose, and a God who has constructed reality to make it so? Well, that’s a whole different thing! Then, a human being’s words DO matter, because they either point towards or away from that ultimate, objective reality that created us. They either help us to get closer to it, or further away. They help or hinder. Words become more than just physical motions and sounds. They become pointers to the objectively real.
If something in the Universe ultimately matters, then we can do science, we can understand morality, and art moves us for a reason.
How interesting that everyone talks as if their words matter, and their thoughts are significant. Perhaps this fact about how we speak – and the assumptions we make about the importance of our words and thoughts – undermines the whole enterprise of atheism and shows it to be self-refuting? Because unless there is a God … our lives are meaningless. But if there is nothing but physical matter – whatever I believe about anything (God included) doesn’t matter and isn’t true or false. So atheism becomes a self-refuting and pointless exercise.
That doesn’t sound like the world we actually live in…
