 In this sense, Agrippa defines faith as the “foundation of reason” (fundamentum rationis), that is, the criterion, guarantee, and firm basis of human knowledge. Revelation is without doubt the absolute and complete expression of truth; but it originates from the same source as the contents of the mind, on which the activity of reason is dependent. Since God is the sole source of truth, the tradition of faith is homogeneous with philosophical contemplation, which finds its justification in revelation. Through divine will, rationality and its higher level of “spiritual intelligence” are able to establish a relationship of continuity. For this reason, rational science and all its practical applications gain authenticity and legitimacy if they develop within a theological framework. This does not mean that reason has to draw its contents directly from Scripture. Rather, it means that the contents of science, procured by the exercise of reason, are “true” when they do not contradict divine design, do not hinder the spiritual progress of the Christian, and contribute to the good of humanity and the world. Certainly, the architect will not seek technical instructions for how to put up his building in the Bible. Instead, he and those who commission him need to seek in it an indication of the “manner” (modus) and “end” (finis) of this discipline. Architecture would be an art and science “extraordinarily necessary and beautiful” in itself and capable of making a large contribution to the well-being of the civil community, if humankind had not rendered it vain and noxious by their excessive use of it “for the simple exhibition of the riches” and by heedlessly destroying the natural surroundings.
