The appreciation of going out to the Other is also appreciated by other philosophers, and not just Levinas. For Plato, philosophy is not just an monologue but is a gradual ascent to the beyond where the gods are. Philosophy is a dialogue with the gods. We also find this sentiment echoed in Descartes, especially when he discusses the Idea of the Infinite.
Descartes noted that philosophy did not make any progress at all because philosophers disagreed about everything. He thought philosophy did not have the right method. He wanted to try to find the indubitable truth, the truth that cannot be doubted, and once it is found, it will be the foundation where he will deduce other truths of philosophy.
He begins by doubting everything. He cleared the table and started with a clean slate. He began with what he calls the universal methodic doubt. He begins to doubt everything: the world, the body, and God. He did not really believe that there was no God, world, or body. It means that he provisionally put world, God, and body in brackets and set it aside. He concluded the methodic doubt by saying that he can doubt everything, but in doubting I know I exist. This is the famous ‘ I think, therefore I am.’ Descartes ended up simply as a thinking something. I can doubt everything but there is one thing I cannot doubt: that I am, and I have ideas.
Descartes is certain that he has ideas: the idea of himself, other people, and God. But he is not yet sure if these ideas correspond to an external reality. Where do these ideas come from? All these ideas, except for the idea of myself and of God, I could have made up myself. Where did I get the idea of God? He described this idea of God as an infinite substance, eternal, immutable, independent, omniscient, and all-powerful. This idea of God in Descartes is the traditional idea in metaphysics.
Descartes concludes that the idea of the Infinite could only have been put in him. It couldn’t have been produced by him because the human being is a limited being, and as a limited being it cannot think of something greater than itself. The effect (the infinite) cannot be greater than the cause (finite human being). The infinite here must be a positive infinite, it is because of this positive idea of the infinite that I realize that I am imperfect.
Descartes idea of God is that God is perfect. If one does not say that God exists, then I’m not really thinking about God because God should have the perfection of perfections—that is, existence. This idea of God is unique because if I think of this idea, I think of something greater than the idea in my head. If one thinks God, it explodes the mind. There is a content which cannot be contained and it cannot stay completely in the mind.
What is the essence of a triangle? Its essence is to have three angles, but I cannot immediately conclude that the triangle exists because its essence does not necessarily include existence. But with the idea of God, his essence necessarily includes existence. Descartes is saying that of all these ideas, the idea of God is the unique idea because its essence necessarily includes existence. This is how he proves that God exists. Knowing that the all-powerful and all-good God exists assures me that he will not deceive me.
Levinas
Levinas is not interested in the traditional idea of God; but he is interested in the container-contained schema. To know is to have ideas which correspond to external reality. Levinas is making the analogy that just as the idea of God cannot be reduced to the container-content, the experience of the Other is also an experience of the infinite because when I experience the Other, the Other escapes my grasp and therefore he overflows, and he cannot be contained simply in my mind. Therefore, the other is somehow infinite.
Part of self-knowledge is knowledge that one is related to one higher than oneself. But this relation is forgotten. To know oneself as related to another. Levinas is trying to show that if you only reflect upon yourself, you already have the mark of others in you. Everybody else that came before me. Why should I be responsible? Because others have already responded for me.
Descartes’ argument have similarities to St. Anselm’s ontological argument. Here’s a link that could help you understand why existence is in the essence of God. Press ENTER to proceed to the next ‘slide’. 🙂
