Key Differences
Logical thinking is strictly based on formal principles of reasoning, like those found in mathematics and formal logic. In contrast, reasonable thinking often incorporates empathy, ethics, and practical constraints which may not strictly adhere to formal logic.
Logical processes typically require consistency and a strict adherence to predefined rules or systems. On the other hand, reasonable decisions may allow for flexibility and adaptability, taking into account human factors and real-world variations.
In debate, a logical argument is valued for its rigorous construction and basis in universally accepted truths. Whereas, a reasonable argument might be appreciated for its fairness, common sense, and accessibility to the average person.
Logical conclusions are reached through deductive reasoning, ensuring the outcome strictly follows from the premises without deviation. Conversely, reasonable conclusions might involve inductive reasoning, drawing generalizations based on observations, which are sensible but not infallible.
While logical can sometimes be seen as cold or impersonal due to its strictness, reasonable is often perceived as warmer and more practical, as it is grounded in everyday realities and human experiences.
