Who analyzed how people used and could use logic?

The philosopher Aristotle is often credited with analyzing how people used and could use logic, particularly through his works on syllogism and deductive reasoning. He laid the groundwork for formal logic, exploring the principles of valid reasoning and argumentation. Additionally, thinkers like Gottfried Wilhelm Leibniz and later logicians, such as George Boole and Bertrand Russell, expanded on these ideas, further developing the field of logic in various contexts.
