Can someone check these two paragraphs, please? It is really important to me.

1)In Chapter ten Dr Jekyll comes to the realization of the primitive duality of man. He admits that man is not truly one but two. He is sure that if he can separate his two identities, he will be able to enjoy both lives without guilt or shame. Well before his scientific discoveries, he had daydreamed (?) of separating the good and evil sides which are part of his personality.
2)Robert Louis Stevenson was born in Edinburgh in 1850. He spent most of his childhood in bed because of his poor health and grew up under the influence of his family’s Calvinism.
