Scientists and business leaders who care about social justice should join forces with environmental and religious organizations to give political *clout to ethics. Science and religion should work together to abolish the gross inequalities that prevail in the modern world.. That is my vision, and it is the same vision that inspired Francis Bacon 400 years ago, when he prayed that through science God would “endow the human family with new mercies." (カ)
