From the standpoint of science...
From the standpoint of science, the universe is like an old book the first and last pages of which have been lost. Neither the beginning nor the end is known. Thus, the worldview of science is a knowledge of the part, not of the whole. Our science acquaints us with the situation of some parts of the universe, not with the shape, mien, and character of the whole universe.
The scientist's worldview is like the knowledge about the elephant gained by those who touched it in the dark, The one who felt the elephant's ear supposed the animal to be shaped like a fan; the one who felt its leg supposed it to be shaped like a column; and the one who felt its back supposed it to be shaped like a throne.
Another shortcoming of the scientific worldview as a basis for an ideology is that science is unstable and unenduring from a theoretical standpoint, that is, from the standpoint of presenting reality as it is or of attracting faith to the nature of the reality of being. From the viewpoint of science, the face of the world changes from day to day because science is based on hypothesis and experiment, not on rational and self-evident first principles.
Hypothesis and experiment have a provisional value; so the scientific worldview is shaky and inconsistent and cannot serve as a foundation for faith. Faith demands a firmer, an unshakeable foundation, a foundation characterised by eternity.
The scientific worldview, in accordance with the limitations that the tools of science (hypothesis and experiment) have inevitably brought about for science, falls short of answering a series of basic cosmological questions that an ideology is obliged to answer decisively, such as: Where did the universe come from? Where is it going? How are we situated within the totality of being? Does the universe have a beginning and an end in time or in space?
Is being in its totality right or a mistake, true or vain, beautiful or ugly? Do inevitable and immutable norms preside over the universe, or does no immutable norm exist? Is being in its totality a single living, conscious entity, or is it dead and unconscious, man's existence being an aberration, an accident? Can that which exists cease to exist? Can that which does not exist come into existence? Is the return of that which has lapsed from existence possible or impossible?
Are the universe and history exactly repeatable, even after billions of years (the cyclical theory)? Does unity truly preside, or does multiplicity?
