- Polizeipräsident: What do you think of Dr.Hirschfeld?
- Adolf Brand: A lonely man. As lonely as all heartbreakers.
- Polizeipräsident: What do you think of Dr.Hirschfeld?
- Baron von Teschenberg: A lonely man. As lonely as all heartbreakers.
- Richard: I am here to learn something concrete, Magnus. It's about science, not about emotions.
- Magnus Hirschfeld: Why can't the one have something to do with the other? Like our friendship for example. Is it perverted?
- Richard: No. Love is a noble quality. Sexual perversion is not.
- Magnus Hirschfeld: Ah, and why not?
- Richard: It is not normal. It serves no natural purpose.
- Magnus Hirschfeld: And what purpose does love serve?
- Richard: It is one of the highest idals of our German culture. And sexual intercourse is surely not a part of.
- Magnus Hirschfeld: Writing off is not either.
- Richard: What do you mean by that?
- Magnus Hirschfeld: That love can be explored in multiple ways. One let themselves bred, the others copy the homework. What is the difference?
- Onkel von Hirschfeld: [reading a book] I am quoting Nitzsche: "What is natural cannot be imoral.
- [closes the book]
- Onkel von Hirschfeld: Who is Nitzsche anyway?
- Magnus Hirschfeld: [being in a gay bar while two men kiss] That two men can be so gentle to each other, why is this against the law.
- Polizeipräsident: Mr. Doctor, I really have enough of this.
- Magnus Hirschfeld: What is it?
- Polizeipräsident: Everything is clean here. Nobody is rubbing each other between the legs. Nobody spits on the floor. Nothing but nice, friendly people.
- Magnus Hirschfeld: What's wrong with that?
- Polizeipräsident: I wanna see Sodom and Gomorrah.
- Magnus Hirschfeld: This is reality, Mr. Police president. These people are people, nothing more.
