Logical vs. Practical: What's the Difference?
Edited by Janet White || By Harlon Moss || Published on November 29, 2023
Logical pertains to formal reasoning; practical relates to real-world application or feasibility.
Key Differences
Logical thinking refers to the use of structured reasoning to come to a conclusion. It involves a systematic process of thinking where conclusions follow from premises according to the rules of logic. For example, if all mammals breathe air, and a whale is a mammal, then it is logical to conclude that whales breathe air. Practical thinking, on the other hand, is concerned with the actual practice or application of an idea, focusing on what is effective or actionable in real-life situations. So, while it’s logical to conclude that whales breathe air, it's practical to consider how this fact affects their behavior and habitat.
The logical approach is often theoretical, relying on data, models, and deductive reasoning to arrive at a conclusion. Logical reasoning is essential in fields that require critical thinking, such as mathematics and philosophy, where principles and arguments must follow a coherent pattern. Practical thinking is more experiential and often empirical, concerned with the workability of solutions or ideas in actual scenarios. For instance, a practical person may prioritize a solution that is viable and cost-effective over one that is theoretically perfect but difficult to implement.
A logical argument may not always lead to a practical solution, as logical validity does not guarantee effectiveness in the real world. An argument that is logically sound is one where the conclusion necessarily follows from the premises. However, a practical argument evaluates the applicability and practicability of the conclusion, considering constraints such as resources, time, and context. While logical correctness is an absolute concept, practicality can vary according to the specific conditions and requirements of a situation.
The realm of logic values consistency, non-contradiction, and formality. Logical correctness is judged independently of the observer’s beliefs or the subject matter's utility. In contrast, practicality values utility, efficiency, and feasibility. Practical solutions are often judged based on their results and ease of implementation, taking into account human needs and limitations. Therefore, while logical statements are evaluated for their intrinsic coherence, practical statements are evaluated for their extrinsic effectiveness.
In the field of computer science, logical processes refer to the computational and algorithmic foundations that underpin software and hardware operations. Everything in computing must follow strict logical rules to function. In the same field, practical considerations might focus on user interface design, where the usability and efficiency for the end-user are paramount. What is logical in code may not always be the most practical in terms of user experience.
