Logical deduction is a reasoning process that involves drawing conclusions based on premises or facts. It allows individuals to arrive at new information by applying established rules of logic. For example, if we know that all humans are mortal and that Socrates is a human, we can deduce that Socrates is also mortal. This method is fundamental in various fields, including mathematics, philosophy, and computer science. Logical deduction helps in problem-solving and decision-making by ensuring that conclusions are based on sound reasoning rather than assumptions or emotions.
