Is the Qur'an notion of Oneness fundamentally different than previously held notions (Hindu, Greek, Xian, Buddhist, etc...)
Something like:
The Oneness of the cosmos is articulated through the oneness of the logos. This oneness of the logoes is not a simple unity, but is involved intimately in the flux of existence.
OR
The consequent Oneness of Being was recognized throughout antiquity as a fundamental tenet of the Eleatic school. The Eleatics maintained that the true explanation of things lies in the conception of a universal unity of Being. According to their doctrine, the senses cannot cognize this unity, because their reports are inconsistent; it is by thought alone that we can pass beyond the false appearances of sense and arrive at the knowledge of being, at the fundamental truth that the All is One.
