Final answer:
The development of a speech topic that argues sexual harassment is morally wrong and should be stopped is a speech proposition of value, which addresses judgments of morality or ethics.
Step-by-step explanation:
If you develop a speech topic that sexual harassment is morally wrong and therefore should be stopped, you are using a speech proposition of value.
This type of proposition is concerned with whether something is good or bad, right or wrong, rather than stating an objective fact or proposing a specific course of action. When discussing moral issues, it's common to engage in value judgements, which are central to the area of philosophy known as value theory.
In the context of a speech or debate, a proposition of value will typically involve ethical considerations and aims to persuade the audience that a certain belief or behavior is desirable or undesirable based on moral principles.
Unlike propositions of fact, which assert something that can be empirically verified, or propositions of policy, which advocate for a specific plan or course of action, propositions of value focus on the morality or ethical values surrounding an issue.
For example, arguing that sexual harassment is morally wrong does not rely on factual evidence but on the belief that such behavior violates ethical norms and should therefore not be tolerated.
