"Know that this single soul, whose powers or parts are described above, is like matter, and the intellect is its form. If it does not attain its form, the existence of its capacity to receive this form is for naught and is, as it were, futile. This is the meaning of his [Solomon's] statement: Indeed, without knowledge a soul is not good. He means that the existence of a soul that does not attain its form, but is rather a soul without knowledge, is not good."
- Maimonides
