“Since everything that lives is obliged to expend and receive life, there is an exchange of modifications between the living creature and its environment.
And yet, once that vital necessity is satisfied, our species—a positively strange species—thinks it must create for itself other needs and tasks besides that of preserving life. … Whatever may be the origin or cause of this curious deviation, the human species is engaged in an immense adventure, an adventure whose objective and end it does not know. …
The same senses, the same muscles, the same limbs—more, the same types of signs, the same instruments of exchange, the same languages, the same modes of logic—enter into the most indispensable acts of our lives, as they figure into the most gratuitous. …
In short, man has not two sets of tools, he has only one, and this one set must serve him for the preservation of his life and his physiological rhythm, and expend itself at other times on illusions and on the labours of our great adventure. …
The same muscles and nerves produce walking as well as dancing, exactly as our linguistic faculty enables us to express our needs and ideas, while the same words and forms can be combined to produce works of poetry. A single mechanism is employed in both cases for two entirely different purposes.”

“Everything in nature completes its action through its own force and species alone… as, for example, fire by its own force dries and consumes and does many things. Therefore vision must perform the act of seeing by its own force. But the act of seeing is the perception of a visible object at a distance, and therefore vision perceives what is visible by its own force multiplied to the object. Moreover, the species of the things of world are not fitted by nature to effect the complete act of vision at once, because of its nobleness. Hence these must be aided by the species of the eye, which travels in the locality of the visual pyramid, and changes the medium and ennobles it, and renders it analogous to vision, and so prepares the passage of the species itself of the visible object… Concerning the multiplication of this species, moreover, we are to understand that it lies in the same place as the species of the thing seen, between the sight and the thing seen, and takes place along the pyramid whose vertex is in the eye and base in the thing seen. And as the species of an object in the same medium travels in a straight path and is refracted in different ways when it meets a medium of another transparency, and is reflected when it meets the obstacles of a dense body; so is it also true of the species of vision that it travels altogether along the path of the species itself of the visible object.”

Bacon, like Grosseteste, asserts that both the active extramitted species of vision from the eye, and the intramitted species of light from object seen, were necessary for sight.

“I believe every creature is born with the inalienable right of freedom. Freedom to live in its natural environment, with its own kind, making its own decisions. I believe the law should prohibit the enslavement of all non human species for any purpose whatever.”
