Final answer:
A hypothetical imperative is a command that one follows to achieve a specific goal, meaning it has a reason behind it. Unlike categorical imperatives, which are moral rules to be followed universally, hypothetical imperatives are driven by personal desires and objectives.
Step-by-step explanation:
A hypothetical imperative, as defined by the Enlightenment philosopher Immanuel Kant, is a command that we choose to follow in order to achieve a specific end or goal. Thus, what you do has a reason behind it. Kant posited that we follow these imperatives with a subjective rule in mind, like 'study hard to get good grades' or 'save money to buy a house for your family'. A hypothetical imperative is essentially a practical means to fulfill a desire, which is different from a categorical imperative, which is a moral rule that one must follow regardless of personal desires or goals.
