The last universal key to open the door to illumination:

• Mankind assumes that a supreme creator exists.

• This supreme creator has supposedly given mankind reason from his own pure "essence".

• If you believe in that, then this pure essence must be pure reason excluding everything irrational.

• Likewise the reason given to mankind should also exclude everything which is irrational.

• Therefore reason excludes anything irrational.

• If we go by the assumption that the "donor's intention in giving "reason" to mankind is keeping its "creation" pure, and if reason excludes everything irrational, then the exclusion principle dictates that there should be nothing irrational in creation or in existence.

• So the existence of an irrational supreme creator is contrary to reason, and no supreme creator could give orders contrary to reason.

• Consequently if what is called the divine word contradicts reason, either it is not the word of the supreme creator or the supreme creator itself is irrational.

• Being irrational, this supreme creator is also subject to the exclusion principle.

• In other words, reason and the supreme creator cannot coexist.
