Some characters in Daniel Deronda just don't seem to fit in. The novel mostly takes place in an upper-class English world of drawing rooms and high society. We definitely know when there are characters who don't seem to fit the general mold. Klesmer, for one, is described as having pretty exotic looks (just check out his flowing hair). Mordecai doesn't just look different; his intense spiritual beliefs distinguish him from both Christian and Jewish characters alike. The ideas of "foreignness" and "otherness" are central to Daniel's self-discovery too; unlike many other characters who seem to fear people who are different from them, Daniel seems to embrace foreignness. He wants to leave the British university system so that he can go learn about the ways that other people live. It seems that Daniel's appreciation for people who aren't exactly like him is a crucial quality in his search for his own mysterious identity.
Daniel Deronda portrays its Jewish characters in a sympathetic and flattering way.
Daniel Deronda plays upon the same stereotypes of Jewish people that we see in other novels from the 1800s.
