On The Way To Being

The title of my thesis sounds like that we could arrive at Being only through some way .Is it necessary that we need some way to Being? Although we are "Da", as Dasein, the way to Being hasn't opened to us. We must go farther only to find that the "Da"is so far way from the way to Being.Being—who can give an end to it? Or can it be said? Are "This is" and "Being" the same? "This is" doesn't say anything or give out anything.Beginning with the question of "Being as Being", Martin Heidegger pointed out that the History of The Western Pholosophy is The Forgotten History of Being.We are entangled in the world as entangled beings.That we care about something means that we are being and we are on the way to Being in nature.So, the thoughts of my thesis are followings:First, I have analized the backgrouds of the Letter and explained the relative concepts of Dasein's Existenzialiat and certain relevancies to later Heidegger according to the letter's content, and tries to sketch out the clues of Heidegger's thinking.Chapter 1 has drawed an outline of the questions on Technik, Sorge, Dasein and Humanism based on the former part of the Letter.Chapter 2 has drawed an outline of the question on Ethos and Entwurf with relevancy to Existenzialiat and later Heidegger. Chapter 3 has drawed an outline of the thinking of Seinsfrage and the relevancy to Denken.
