Final answer:
The correct answer is True. According to Aristotle's philosophy, it is true that some products are means to an end, others are both ends and means, and still others are only ends, which corresponds with his conception of the four causes and the ultimate goal of eudaimonia.
Step-by-step explanation:
The statement asking about Aristotle's conception of products as means to an end, end and means, or only ends relates to his teleological perspective, where he identifies four causes to understand nature and the universe. The material cause concerns what something is made of, the formal cause refers to its shape or essence, the efficient cause is the agent responsible for creating it, and the final cause is the end goal or purpose for which something is done.
True to Aristotle's views, some products (or actions) could be considered merely means to an end, such as money used to purchase necessities. Others could be seen as both ends and means, like knowledge which is valuable in itself and can also lead to further ends.
And there are those which are seen as only ends, these are often inherently valuable pursuits or objects that are sought for their own sake, such as eudaimonia (flourishing life), which Aristotle argues is the ultimate goal of human action.
Thus, in light of Aristotle's philosophy and the provided context, the statement can be considered true.
