1external world, first sensed by the sense organs and then perceived by my brain, reach my I or consciousness in the form of mental images, and it is upon these mental images or, better said, availing itself of them, that my I creates concepts and ideas.
2This is the work of thought, its specific activity, which gives origin to its products: ideas.
3But those ideas are not my I — first, because they are the product of my faculty of thinking, and then because I can refrain from producing them or, once produced, reject them from my consciousness.
4Thought has, moreover, another object: unlimited space.
5Space does not usually depend on the activity of the five senses, but is known immediately by “pure thought” when the activity of the senses is temporarily suspended.
6Space is, in reality, the immediate object of thought and, when we begin to think, space presents itself immediately to us.
7As soon as thought is set in motion by an activity of the senses, we necessarily perceive space as well.
8We cannot know any object that falls under the action of the senses without knowing at the same time the space within which that object is found [Editorial gloss: the Spanish prints a duplicated phrase, “los sentidos sin conocer al mismo tiempo”, transmitted as a compositor’s doubling].
9Inversely, we can know space alone (without other objects) when we suspend the activity of the five senses and concentrate thought solely upon that space.
10We have, then, the perception of unlimited space, and we can even separate space from our thought and, in spite of that, continue thinking.
11But to accomplish this prodigy we must completely suspend the activity of the senses and concentrate thought exclusively upon this idea: “Nothing now exists for me”.
12Space itself can then be eliminated from consciousness, only the thought subsisting: “Nothing more exists”.
13And not only is it possible to eliminate space from consciousness, but we can further recognise directly and in a perfect manner that space has, objectively, nothing in common with my I.
14To give an example, let us imagine an impossibility: all the space outside my body is annihilated.
15This fact would not affect me at all.
16Now it remains for us to know whether the space occupied by my body is essential to me.
17Let us imagine that this body, always keeping its vitality, shrinks until it reaches the dimensions of an insect.
18And shall “I myself” not be diminished by this reduction of my body, a reduction that has as its consequence the diminution of the space occupied by it?
19I should still recognise myself as “I myself” (identically like the one I have always been) despite my more reduced body and the likewise more reduced space occupied by it.
20Thus, with this example it is demonstrated that space has nothing in common with my I.
21Space is simply a condition of the existence of my body.
22This further clarification made, we can establish another point of study with the following definition: THE BODY IS NOT MY I Within what relation do I stand with my body?
23The body is a physical organism consisting entirely of materials of exterior nature, taken and assimilated in
