Coming from a secular agnostic family background, I have been an atheistic materialist and naturalist for most of my life until my late thirties, and was only interested in nature
and natural sciences. Due to my interest in modern physics (cosmology, relativity theory, and quantum mechanics) I came to realize fundamental philosophical problems concerning time, causality,
and the effectiveness of mathematics, which were supplemented by the hard problem of consciousness. After more than a decade of philosophical/metaphysical search for a coherent
world view involving temporary commitments to various views like panentheistic neopaganism, integral thought (Ken Wilber), process thought (Whitehead), neoplatonism with objective idealism (John
Leslie), deism, and generic classical theism, I finally converted to Roman Catholicism in my early fifties, after a few troublesome years of residual doubt with epicycles of belief and unbelief
(incl. denominational confusion). My conversion to Christianity, by the grace of God and the guidance of the Holy Spirit, did not involve any (blind) faith in scripture, but was purely based on
reason and a careful and critical evaluation of empirical evidence as well as philosophical arguments.
