Consider Hippocrates, the physician.  He was one of the eminent philosophers who believed in God and acknowledged His sovereignty.  After him came Socrates who was indeed wise, accomplished and righteous.  He practised self-denial, repressed his appetites for selfish desires and turned away from material pleasures.  He withdrew to the mountains where he dwelt in a cave.  He dissuaded men from worshipping idols and taught them the way of God, the Lord of Mercy, until the ignorant rose up against him.  They arrested him and put him to death in prison.  Thus relateth to thee this swift-moving Pen.  What a penetrating vision into philosophy this eminent man had!  He is the most distinguished of all philosophers and was highly versed in wisdom.  We testify that he is one of the heroes in this field and an outstanding champion dedicated unto it.  He had a profound knowledge of such sciences as were current amongst men as well as of those which were veiled from their minds.  Methinks he drank one draught when the Most Great Ocean overflowed with gleaming and life-giving waters.  He it is who perceived a unique, a tempered, and a pervasive nature in things, bearing the closest likeness to the human spirit, and he discovered this nature to be distinct from the substance of things in their refined form.  He hath a special pronouncement on this weighty theme.  Wert thou to ask from the worldly wise of this generation about this exposition, thou wouldst witness their incapacity to grasp it.  Verily, thy Lord speaketh the truth but most people comprehend not.

After Socrates came the divine Plato who was a pupil of the former and occupied the chair of philosophy as his successor.  He acknowledged his belief in God and in His signs which pervade all that hath been and shall be.  Then came Aristotle, the well-known man of knowledge.  He it is who discovered the power of gaseous matter.  These men who stand out as leaders of the people and are pre-eminent among them, one and all acknowledged their belief in the immortal Being Who holdeth in His grasp the reins of all sciences.

I will also mention for thee the invocation voiced by Balinus who was familiar with the theories put forward by the Father of Philosophy regarding the mysteries of creation as given in his chrysolite tablets, that everyone may be fully assured of the things We have elucidated for thee in this manifest Tablet, which, if pressed with the hand of fairness and knowledge, will yield the spirit of life for the quickening of all created things.  Great is the blessedness of him who swimmeth in this ocean and celebrateth the praise of his Lord, the Gracious, the Best-Beloved.  Indeed the breezes of divine revelation are diffused from the verses of thy Lord in such wise that no one can dispute its truth, except those who are bereft of hearing, of vision, of understanding and of every human faculty.  Verily thy Lord beareth witness unto this, yet the people understand not.
