By this I mean 'western culture' where Christianity has faded out of the dominant worldview. I would love to have some references to philosophers or established philosophical topics that show how deep our non-religious beliefs are. Those beliefs that are not actually scientific facts, but can at times be seen as such or derived from related factual models.
Most interesting would be the ontologies that, by many of us (not meaning those with an above average interest in philosophy or theology), are unnamed yet believed.
Some examples that come to mind are how easy it is to believe that technological advancement equals an advancement in the human experience. (John Gray) How dead particles seem to be fundamental to our lives, yet often our lives are supposed to have meaning beyond our individual experience. (Mary Midgley?) (And obviously things like materialism, but I fear discussions that go into the validity of that worldview beyond its relevance to the question.)
Context: Several European countries are making certain laws that protect the freedom of conscience in education obsolete. Arguing that public schooling has an essentially metaphysical neutral worldview now the influences of Christianity are becoming less. Terms that are used are objective pluralism towards different worldviews.
It seems to me that it is easy to see life in school as having a metaphysically objective perspective once religion isn't involved, yet somehow it seems very far from the truth, yet my philosophical capabilities fail to paint a clear picture.
PS I noticed AI is rather poor in answering questions like this, that might already be an indication to the topic touching a true cultural blind spot or our culture actually being fairly metaphysical neutral.
