Final answer:
The Kantian Categorical Imperative is based on human reason, making the answer to the question A. True. Kant's moral philosophy centers on the ability of rational beings to create universal moral laws through reason, aiming for actions that can be universally applied.
Step-by-step explanation:
The Kantian Categorical Imperative indeed originates from human reason, which makes the answer to the student's question A. True. Immanuel Kant, an Enlightenment philosopher, posited that as rational beings, we can establish universal moral laws or maxims through the use of our reason. Central to his moral philosophy is the idea of the Categorical Imperative, which asserts that one should "Act only according to that maxim whereby you can, at the same time, will that it should become a universal law". This principle intends for individuals to behave in a way that could be applied to everyone universally, thus endorsing a form of moral law derived from rationality itself.
According to Kant, moral actions are not dependent on the consequences they produce but are grounded in the intention behind the action. He introduced the concept of goodwill, defining it as our capacity to rise above our instincts and make decisions based on rational thought. Kant's framework for ethics relies on a priori reasoning to reach moral conclusions that translate into duties everyone should follow, irrespective of personal desires or societal influences.
