"Science and the Infinite; or, Through a Window in the Blank Wall" by Sydney T. Klein As a scientist and science writer, Klein aims to make cerebral concepts easier to digest even for people who aren't active in the field. Though some ideas are a bit outdated due to newer scientific perspectives and discoveries, many fit well with contemporary thought and were therefore well ahead of their time including many confirmed by current science such as humans' limited, 3-dimensional observable shadow of the ultimate reality. It covers everything from mysticism to space, many of which are topics that are still relevant today.
