Hi Lal, thank you for sharing. Actually the context behind this question was that I am inspired by how monks in the Jethavanarana Buddhist Monastery were able to explain dhamma concepts to lay people without invoking much of kamma and rebirth, yet they can provide such convincing explanations for the lay person about how the puthujjana way of living is highly flawed. (By the way for those who have been trying to teach dhamma to their friends, i highly recommend their videos, they explain with simple logic which people are more willing to accept)
From here I thought that most problems can be solved without invoking the “wider worldview”. Of course to gain complete understanding, one must also ultimately learn the Noble Truths, Tilakkhana, Paticca Samuppāda.
You also remind me of the reflections from the conversation I had, and watching the sermons is that explaining dhamma concepts to a lay person with just “lay logic” would be a good way to comprehend the dhamma. That way you can be fully convinced yourself by explaining things with just logic.
However, my other reflection is that if we continue to do this, it may make us stray from the path because ultimately paticca samuppada cannot be understood with “lay logic”, and we won’t contemplate this wider worldview which is necessary for Nibbāna. For example, the second noble truth requires the understanding that attachment leads to birth, with does not follow “lay logic”
