There are two factors that explain how Eco was able to write so much. In his own words, the life of every person has exply spaces- periods with no important jobs. He says that he did most of his writing during these free intervals. Second, he explains that people wondered that he (Eco) had written so much on various subjects. But the fact is that he was writing on the same lines and same interests-peace, non-violence, etc. All his works were linked with the thread of common interests. It saves his time and he could write a lot in a short period of time. That was the secret behind Eco’s prolific pen.
