"knowledge" requires the reader to begin with a Universal Perspective -- a philosophy based on "human-only" effort. This is an appeal to rationalism -- and its appeal to mathematical "science." Universal perspectives are acquired tastes! But with truth larger than science, a Knowledge Advance Spectrum exists and orients the search for truth, beginning with the accessible. Theory-free knowledge begins without mathematics or philosophy. Reasonable people agree. Rational people disagree -- they are lost without that universal perspective. Polyscience and Christianity: Rational Thought's Long History is a prelude on this search for truth. Modern people, sure of there objectivity, think they do not need to know their intellectual history. This oversight warrants this prelude. Imperfect reasoning existed in ancient Greece - in false ideas guiding mathematics, then astronomy. It is an unusual landscape that we will traverse. Rationalists still believe the Universal Perspective to be "Mathematics and Astronomy show that the universe has vast distances and long ages. The subsequent job of geology, biology and psychology is to fill in the details. This is the secular paradigm. But have thinkers outgrown this subjectivity? While science is typically described as in a laboratory setting, many thinkers find that restrictive. Beyond that arena, there is a suspicious wordy subjectivity among rational people. Many "facts" are not theory-free; some require large expenditures of reason. Such "human-only" reasoning frequently produces competing streams of learned gibberish, thus mocking faith and reason. Reasonable people are beginning to see that Christianity is no "god of the gaps" idea. Ex Nihilo creation and empirical science again become the true alternative to rational subjectivity.
