In modernism reason is conceived as a purely human activity, also cut off from the Transcendant and in postmodernism one is set to deconstruct reason by taking hold of and referring to the irrational levels of the human psyche, whereas in traditional sciences the human mind is understood as being a mirror of the Divine Mind. The picture produced on the mirror is the product of the Picture-maker reflecting Itself on it.
Thus tradition has always held that the organ ''and container of knowledge is not the human mind but ultimately the Divine Intellect.'' Therefore ''true science is not based on purely human reason but on the Intellect which belongs to the supra-human level of reality, yet illuminates the human mind.''TIM p.100.
"When Descartes uttered, 'I think, therefore I am (cogito ergo sum), he placed his individual awareness of his own limited self as the criterion of existence, for certainly the 'I' in Descartes' assertion was not the Divine 'I' who, through Hallâj, exclaimed, 'I am the Truth' (ana'l Haqq): The Divine 'I' which alone, according to traditional sources has the right to say 'I'. Until Descartes, it was Pure Being, the Being of God, which determined human existence and the various levels of reality. But with Cartesian rationalism, individual human existence became the criterion of reality and also the truth." TIM p.100
And what could be of more success to earthly man than to relate his intellect to the higher Intellect which is not of his own and which is unrestricted and independant of place and time. ( Quran 24-19 )
