By 'seeing all things that belong to the perfection of the universe,' St Thomas would mean, in modern terminology, 'having a comprehensive scientific view of the universe as a whole': this would include knowledge of the constitution of matter, and of its working arrangements, molar and molecular; and understanding of electricity, of gravitation, of vegetable and animal life, of the genesis of nebulae and stars, of the origin of species, animal and vegetable, of the workings of the mind, such as free will. A very wonderful knowledge, but much less wonderful than the vision of God.
