The emergence of such a being requires a comprehensive reform of the human being, involving various changes such as the negation of false values and meaningless criteria deriving from the Age of Ignorance and the creation and fostering of a creative energetic spirit within him. The Quran can thus be said to melt the spirits of human beings and pour them into a new mould, where they acquire a different, richer and more valuable form. Through the inspiration given by the Quran and as a result of the scientific movement launched by Islam, a vital and active people blossomed into maturity, uniquely gifted with knowledge and virtue. The viewpoint of Islam on science represented a major development that prepared the way for subsequent developments. The constant appeal to reason and experience in the Quran, and the emphasis that it lays on Nature and History as sources of human knowledge, are all different aspects of the same idea of finality.
Inner experience is only one source of human knowledge.
All forms of scientific endeavor are necessarily based on respect for the intellect and for the development of the human being and on freedom of thought from all kinds of fetters. The principal advances and developments in the natural sciences are all due to these premises. The contemporary human being is heir to the knowledge and the researches of millions of thinkers and scholars who in their investigations discovered the foundations of the various sciences, and who gained access to some of the mysteries of being by means of their intellectual originality and creativity and their untiring efforts. When expounding the mysteries of creation, the Quran is clear and explicit whenever clarity and explicitness are desirable. In cases where the perception of complex truths was difficult for the people of that age, the Quran contents itself with making allusions, so that in the course of time as the intellects and knowledge of human beings developed and the mysteries of nature came more clearly to the fore, these matters would become more easily comprehensible.
