Affirmation and negation can not coexist together. A thing can not both be created and also existent from eternity, living and annihilated simultaneously, at once necessary and impossible." To this the notions I derived from my senses made the following objections: "Who can guarantee you that you can trust to the evidence of reason more than to that of the senses? You believed in our testimony till it was contradicted by the verdict of reason, otherwise you would have continued to believe it to this day. Well, perhaps, there is above reason another judge who, if he appeared, would convict reason of falsehood, just as reason has confuted us. And if such a third arbiter is not yet apparent, it does not follow that he does not exist."
To this argument I remained some time without reply; a reflection drawn from the phenomena of sleep deepened my doubt. " Do you not see," I reflected, " that while asleep you assume your dreams to be indisputably real? Once awake, you recognize them for what they are baseless chimeras. Who can assure you, then, of the reliability of notions which, when awake, you derive from the senses and from reason? In relation to your present state they may be real; but it is possible also that you may enter upon another state of being which will bear the same relation to your present state as this does to your condition when asleep. In that new sphere you will recognize that the conclusions of reason are only chimeras."
This possible condition is, perhaps, that which the Sufis call " ecstasy " (hal), that is to say, according to them, a state in which, absorbed in themselves and in the suspension of sense-perceptions, they have visions beyond the reach of intellect. Perhaps also Death is that state, according to that saying of the prince of prophets: " Men are asleep; when they die, they wake." Our present life in relation to the future is perhaps only a dream, and man, once dead, will see things in direct opposition to those now before his eyes; he will then understand that word of the Koran, " To-day we have removed the veil from thine eyes and thy sight is keen."
