Final answer:
The claim is false; Jeremy Bentham and other theorists who believed in the creation of rights by the state explicitly recognized welfare rights, in contrast to some Natural Rights theorists.
Step-by-step explanation:
The statement that No Natural Rights theorist ever acknowledged the need for Welfare (Positive) Rights is false. While philosophers like John Locke emphasized natural rights that are inherent and inalienable, others such as Jeremy Bentham challenged the very existence of natural rights. Bentham, who was known for his utilitarian approach, argued that rights are a creation of the state, suggesting that rights come into existence within the context of laws and government. This perspective opens the door to positive rights, including welfare rights, which are provided and protected by the state and can contribute to achieving the greatest good for the greatest number of people. Moreover, later philosophers and theorists who supported welfare liberalism also recognized the legitimacy of welfare rights, thus acknowledging both natural and positive rights.
