Science May Set Limits To Knowledge, But

Be Isolated, Be Ignored, Be Attacked, Be In Doubt, Be Frightened, But Do Not Be Silenced.

Thought Is Merciless To Privilege, Established Institutions, And Comfortable Habit.

Aristotle, In Spite Of His Reputation, Is Full Of Absurdities. He Says That Children Should Be Conceived In The Winter, When The Wind Is In The North, And That If People Marry Too Young The Children Will Be Female. He Tells Us That The Blood Of Females Is Blacker Than That Of Males; That The Pig Is The Only Animal Liable To Measles; That An Elephant Suffering From Insomnia Should Have Its Shoulders Rubbed With Salt, Olive-oil, And Warm Water; That Women Have Fewer Teeth Than Men, And So On. Nevertheless, He Is Considered By The Great Majority Of Philosophers A Paragon Of Wisdom.
