Final answer:
Thomas Hobbes' social contract theory is not a form of rule-ethical-egoism; instead, it posits that individuals consent to authority to ensure peace and stability, which is in their self-interest but not inherently egoistic. The correct answer is False.
Step-by-step explanation:
The statement that Thomas Hobbes developed a normative theory known as social contract theory, which is a type of rule-ethical-egoism is False. Hobbes' social contract theory does involve self-interest insofar as individuals seek to avoid the brutish state of nature by consenting to an absolute sovereign, but it is not accurately characterized as rule-ethical-egoism. Rather, Hobbes posited that in order to escape a life that is 'solitary, poor, nasty, brutish, and short,' individuals consent to an authoritarian ruler to ensure peace and societal stability. This surrender of rights is not for the sake of ethical egoism, but for the benefit of mutual protection and order.
