When he says the world comprises of 7 planets, that is science and not metaphysics. He says that the Universal Souls comprises of seven creative principles which created 7 planets. That was the wordview of the time.tret wrote:Nasir Khusraw explains it in accordance with meta physics and not scientifically. Even today the scientific community doesn't have a concrete answer to this [dense coming into existence from subtle].
And this outlook is shared between all the Ismaili philosophers/thinkers/Dais and Hujjats of the Ismailis, including Tusi, Al-Sijistani. As Al-Sijistani explains that the function of the Universal Soul is Tarkib [Composition] of the matter with form, as Nasir Khusraw explained in his Knowledge and Liberation.
If he had said that the Universal Soul created the world (without mentioning the 7 planets and the 7 principles), then we could apply it universally, but he mentioned 7 planets (including the sun and the moon)which means he was describing the world as understood in his time.
The scientific community today is quite clear that the sub-atomic world is not comprised of particles but rather subtle probabilities of existence. Hence there is no division between the subtle and the dense (which is the product of the illusory maya).
As I mentioned before, the 49th Imam has said that there is no difference between the soul and body - they are one. The soul is the body and does not cause the body as per Nasir.
The agreement of all the Dais of the medieval period does not make the notion right in today's conditions.
