Rhetoric
Rational thought is employing the logic known as 'thinking' or 'understanding' Rational Logic doesn't own the 'knowledge' (experience) about reality. For example, intuition makes a deer identify a human as predator because most humans behave like predators. 'Rational thought' or 'understanding/thinking' is applying of the logic 'rationality', designed in Enlightenment by the Catholic pries Descartes. Since application of 'rational' logic is not limited to facts and also include juggling with abstract notions, 'rationality' can also be without emotion and totally abstract (the law is reason without emotion)
logic
A mathematical technique for dealing with imprecise data and problems that have many solutions rather than one. Although it is implemented in digital computers which ultimately make only yes-no decisions, fuzzy logic works with ranges of values, solving problems in a way that more resembles human logic. Fuzzy logic is used for solving problems with expert systems and real-time systems that must react to an imperfect environment of highly variable, volatile or unpredictable conditions. It "smoothes the edges" so to speak, circumventing abrupt changes in operation that could result from relying on traditional either-or and all-or-nothing logic.
The word that means without logic is "illogical." It describes reasoning or actions that lack sound reasoning or coherence, often appearing irrational or nonsensical. Another term that can convey a similar meaning is "irrational."
people usually use logic in math and math in logic
Rhetoric
Using logic, emotions, and expert standing to make a point is sometimes referred to as making a persuasive argument or employing ethos, logos, and pathos.
Logic = As much as you have. Emotion = Zero. Zip. Nada. Gut Feeling = 20% (Not to be confused with emotion).
No, logic is not an emotion. Logic is a rational and systematic way of thinking that involves reasoning and making decisions based on evidence and principles, while emotions are feelings or reactions that arise in response to stimuli.
The speaker may use appeals to emotion by eliciting strong feelings in the audience to persuade them. Appeals to logic and common sense involve presenting facts and reasoning to support their argument. Appeals to authority and moral character rely on the credibility and ethical standing of the speaker to persuade the audience.
Aristotle believed in a balance between logic and emotion. He felt that logic was required for strong and valid arguments. Emotions reinforced logical arguments.
