"Fear is the parent of cruelty, and therefore it is no wonder if cruelty and religion have gone hand-in-hand. It is because fear is at the basis of those two things. In this world we can now begin a little to understand things, and a little to master them by the help of science, which has forced its way step by step against the Christian religion, against the churches, and against the opposition of all the old precepts."

There is no word in our language which has been so much misused and prostituted as the word love. It has been preached by those who were ready to condone every cruelty if it served their purpose; it has been used as a disguise under which to force people into sacrificing their own happiness, into submitting their whole self to those who profited from this surrender. [...] It has been made so empty that for many people love may mean no more than that two people have lived together for twenty years just without fighting more often than once a week.
