Counting galaxy number density with wide range sky surveys has been well adopted in researches focusing on revealing evolution pattern of different types of galaxies. As understood intuitively the astrophysics environment physics is intimately affected by cosmology priors with theoretical estimation or vice versa, or simply stating that the astrophysics effect couples the corresponding cosmology observations or the way backwards. In this paper, we try to quantify the influence on galaxy number density prediction at faint luminosity limit from the uncertainties in cosmology, and how much the uncertainties blur the detection of galaxy evolution, with the hope that this trying may indeed help for precise and physical cosmology study in near future or vice versa.

Scientistic conceptualisations hold to the positivistic positions that science is limitless in its potential representations of material phenomena and that it is the only sure path to knowledge. In recent popular scientific literature, these presuppositions have been reaffirmed to the detriment of both philosophy and theology. This article argues for the contrary position by a meta-analysis of empirical science from a Thomist perspective. Identifying empirical science as limited in its method and bound to the material sphere of being alone, we posit that rather than standing as the sole path to the knowledge of being, empirical science is constrained at its frontiers. It is subsequently contended that far from empirical science having the explanatory ability to respond to all presenting scientific problems in principle, fundamentals without the grasp of the methodology of empirical science exist. To relate the article’s meta-analysis to scientific praxis, physical cosmology – as the most foundational empirical science – is exemplified in the discussion.Keywords: Philosophy; Religion; Science; Scientism; Thomism; Metaphysics; Epistemology
