1。 This sentence was said by Hegel, and Sartre only quoted Hegel's words. Others mistakenly thought that this sentence was said by Sartre.
2。 Hegel said this sentence first, and then Sartre said it again, just because they have the same point of view and say the same thing.
In short, Hegel said before Sartre that "existence is reasonable".
Before analyzing these two possibilities, let me correct a mistake. Most people think that Hegel's famous saying means that everything that exists is natural and reasonable, and "existence" is a necessary and sufficient condition for "rationality" (value judgment). At that time, on my blog, my classmate Wen Beibei's message thought so. This misunderstanding probably stems from the fallacy of the translator of the old version of Hegel's works. The correct translation of the original text should be: rational is realistic, and realistic is rational. As a master of classical idealist dialectics philosophy and a thorough objective idealist, Hegel advocates that rationality is the first priority, so he will not say that "existence" is a necessary and sufficient condition for "rationality" (value judgment). Of course, we can't deny that Bei Beiwen understood this sentence as his own meaning, so "everything is reasonable" in Bei Beiwen's mouth is his own view, not Hegel's or Sartre's. We can disagree with him to accept the love between man and beast, but we must respect his idea, but I still hope he will not try.
Now I will analyze the first two possibilities from the following aspects:
1 In chronological order, Hegel was born in Stuttgart, Germany at the end of18th century, while Sartre came to this world at the beginning of 20th century. Hegel and Bisat spoke more than one hundred years earlier, unless Hegel could not speak or write because of some physical defect, of course, this possibility can be directly denied. So this famous saying should be said by Hegel, a German.
From the development history of philosophy, German philosophy from the late18th century to the mid19th century is called German classical philosophy. German philosophers in this period established a magnificent philosophical system, including numerous detailed analyses, meticulous concepts and complicated arguments. Immanuel Kant is an outstanding representative of German classical philosophy. His main work is Critique of Pure Reason, which is called "Copernican Revolution in the field of philosophy". Kant put forward "innate comprehensive judgment", which combines empiricism and rationalism and demonstrates how innate comprehensive judgment is possible. Hegel established his own system on the basis of criticizing Kant's agnosticism, which is considered to be the first and largest system in the history of philosophy. The history of western philosophy takes Hegel as the logical end point, and the later period is the development period of modern western philosophy.
Sartre, as the founder of existentialist literature in modern western philosophy, went to Berlin in 1933 and studied hard under the famous German philosophers Husserl and Heidegger. Heidegger has a decisive influence on existentialism, deconstruction, hermeneutics, postmodernism, political theory, psychology and theology. As a German philosopher, Heidegger's thoughts were also influenced by Kant, Hegel, Nietzsche, Soren Ober Kierkegaard and others. As can be seen from the history of philosophical development, Heidegger, Sartre's teacher, was also influenced by Hegel's thought, so the famous saying "Being is reasonable" should be said by Hegel first, and Sartre expressed it in similar language a hundred years later, and later people mistakenly thought that this sentence was said by Sartre.
As far as personal style is concerned, Sartre has the romantic nature of the French, and he has been romantic since he was a child. He is a famous playboy, who has numerous lovers all his life and is said to have been gay. I don't know if you know Beauvoir. She is a famous feminist and the author of The Second Sex. For her, Sartre once laughed at a young rock singer. Sartre is called a philosopher or a famous contemporary French writer. As a romantic young literary playboy, Sartre should not say such simple words as "Being is reasonable". It is said that Sartre's style of writing is beautiful and gorgeous, and talking about philosophy is like writing a love letter, which is enough to prove that this sentence is probably said by the rigid and rigorous German old man Hegel.
