Anaxagoras, who received his learning from Anaximenes, was the first who affirmed the system and disposition of all things to be contrived and perfected by the power and reason of an infinite mind; in which infinity he did not perceive that there could be no conjunction of sense and motion, nor any sense in the least degree, where nature herself could feel no impulse.

If he would have this mind to be a sort of animal, then there must be some more internal principle from whence that animal should receive its appellation.

But what can be more internal than the mind?
Let it, therefore, be clothed with an external body.

But this is not agreeable to his doctrine; but we are utterly unable to conceive how a pure simple mind can exist without any substance annexed to it.
Alcmaeon of Crotona, in attributing a divinity to the sun, the moon, and the rest of the stars, and also to the mind, did not perceive that he was ascribing immortality to mortal beings.
Pythagoras, who supposed the Deity to be one soul, mixing with and pervading all nature, from which our souls are taken, did not consider that the Deity himself must, in consequence of this doctrine, be maimed and torn with the rending every human soul from it; nor that, when the human mind is afflicted (as is the case in many instances), that part of the Deity must likewise be afflicted, which cannot be.

If the human mind were a Deity, how could it be ignorant of any thing?
Besides, how could that Deity, if it is nothing but soul, be mixed with, or infused into, the world?
Then Xenophanes, who said that everything in the world which had any existence, with the addition of intellect, was God, is as liable to exception as the rest, especially in relation to the infinity of it, in which there can be nothing sentient, nothing composite.
Parmenides formed a conceit to himself of something circular like a crown.
