The soul's movement proves its existence; the body's cessation proves it is separate matter.Listen — Srila Prabhupada Uvaca
Śyāmasundara: This morning we are discussing a philosopher called Ludwig Wittgenstein, a contemporary German philosopher. One of his major so-called contributions is what is called a verification principle, which reads, "To understand a proposition means to know what is the case if it is true." That means in order... anyone who wishes to understand a proposition must first
know the conditions under which that proposition is true, that is, what information is required by way of evidence of its truth.
Prabhupāda: So the modern world's proposition is that "I am this body." So that is untruth. What does he say about this?
Śyāmasundara: Well, if I claim that I am this body, that means I have to know all of the conditions which make it true that I am this body. Then if all these conditions are true...
Prabhupāda: First of all we must discuss what I am. Then we have to see whether I am this body or not. And what do you mean by "I am"? You are individual, I am individual. How I exact my individuality, and how you exact your individuality? What is the symptom? What is the meaning of "I am"? First of all you have to understand, what do you mean by "I am"? "I am" means my activities, "I am." That is "I am."
Prabhupāda: Yes. So try to understand, "I am" means my activities. So how my activities are going on? Presently we can see my activities are going on by the movements of my senses, of the limbs of the body. Therefore we come to the point that the moving force is "I am."
Śyāmasundara: That which moves the limbs.
