What are the motifs in The Book of Disquiet by Fernando Pessoa?

Relationship with others is a recurring idea. Although Soares does not have much interaction with other people, he often makes comments about the way he believes other people perceive him. For instance in Section 107 Soares writes that he believes he has the sort of soul that women love. However, he adds that women never recognize him as that type of soul when they meet him. Soares shows another quirk in his personality in Section 170.
