Logical vs. Rational: Know the Difference
By Shumaila Saeed || Published on February 28, 2024
Logical refers to clear, reasoned thinking based on facts and inference, while rational is based on reason or logic, often involving practicality and the ability to make sound judgments.
Key Differences
Logical implies a methodical or reasoned approach, where conclusions are drawn from established principles or facts. It often involves a step-by-step progression of thoughts. Rational, on the other hand, pertains to reasoning that is sensible and sound, focusing on what is practical or realistic. It encompasses judgments or decisions that are based on reason or logic, but also factors in practicality and feasibility.

In the realm of philosophy and mathematics, logical thinking is highly structured, often following strict principles like syllogisms or mathematical proofs. It adheres to formal rules and is sometimes devoid of emotional considerations. Rational thinking, while also grounded in logic, often incorporates a broader scope, including emotional intelligence and subjective experience, to make decisions or judgments that are not only logically sound but also pragmatic.

The application of logical thinking is prominent in computer programming and formal sciences, where precise and unambiguous reasoning is paramount. Rational thinking, however, is more commonly applied in everyday decision-making, where practicality and efficiency are key, even if it means occasionally deviating from strictly logical procedures.

A logical argument is one where the conclusion necessarily follows from the premises. If the premises are true, the conclusion cannot be false. A rational argument might include the same logical structure, but also considers the relevance and realism of the premises, ensuring that they are not just true, but also applicable and practical in a given context.

Logical thinking is often associated with the objective assessment of facts, where emotion and personal bias are minimized. Rational thinking, while it also values objectivity, does not discount subjective factors such as personal values, beliefs, and experiences, which can play a significant role in decision-making processes.
