In order to have a constructive conversation with another person about any topic of importance, you need to have a good understanding of their basic outlook on life and what ultimately motivates their beliefs and responses. For the same reason, it’s best if the other person has a good grasp of your basic outlook on life and what ultimately motivates your beliefs and responses. Furthermore, to have a really fruitful discussion you need a clear view of the most central and fundamental points of agreement and disagreement between the two of you, and some notion of how to evaluate your differences in a principled way.
When we enter into conversations with unbelievers over controversial topics, we should recognize that any significant disagreements we encounter will often trace back to more fundamental worldview differences. When that’s the case, the most responsible and constructive way forward will not be to try to ignore or bypass those foundational differences, but rather to acknowledge them and lay them out on the table for scrutiny.
