A Fortiori Argument: A Deep Dive into Its Legal Significance

Definition & Meaning

An a fortiori argument is a logical reasoning method that draws a conclusion from a stronger claim to support a weaker one. The term comes from the Latin phrase "argumentum a fortiori," meaning "from the stronger." This type of argument is useful in various contexts, particularly in legal discussions, where proving a point can rely on established, stronger propositions.

Real-world examples

Here are a couple of examples of abatement:

Example 1: If a law allows for a penalty of five years for theft, one could argue a fortiori that a penalty for armed robbery, which is a more serious offense, should be longer than five years.

Example 2: If a court has previously ruled that a child should live with a parent who has a stable job, one might argue that a parent with a more secure and higher-paying job should have even greater custody rights. (hypothetical example)
