The spelling of the word "logical truth" can be explained using IPA phonetic transcription as /ˈlɑːdʒɪk(ə)l truːθ/. The first syllable is pronounced as "lah-djih-kal" with the stress on the first syllable, followed by the second syllable pronounced as "trooth". The "g" in "logical" is silent, and the "th" in "truth" is pronounced as ð. This term refers to a statement that is true based on logical reasoning or deduction, regardless of whether it is empirically observable or not.
A logical truth is a statement or proposition that is universally true, regardless of any particular situation or context. It is a statement that is absolutely correct and cannot be false under any circumstances. In other words, a logical truth is a statement that is necessarily true, meaning it is true in all possible worlds.
Logical truths are a fundamental concept in logic and philosophy. They serve as the foundation for deductive reasoning and logical consistency. They are considered to be a result of the laws and principles of logic, which dictate how valid arguments and inferences are made.
A logical truth can be identified by its characteristic of being self-evident and needing no further evidence or justification. It is often expressed in the form of tautologies, which are statements that are true by virtue of their logical structure alone. For example, "All bachelors are unmarried" or "A square has four sides" are logical truths because they are true by definition and do not depend on any external factors.
Logical truths are distinct from empirical truths, which are based on observation and experience in the physical world. While empirical truths can change or vary depending on circumstances, logical truths remain constant and universally applicable.
In summary, a logical truth is a statement that is necessarily true in all possible worlds, independent of any specific situation or context. It is a fundamental concept in logic and serves as a basis for deductive reasoning and logical consistency.
The etymology of the word "logical" can be traced back to the Greek word "logikos", which means "related to reasoning or intellect". It is derived from "logos", meaning "word" or "reason", which has its roots in "legein", meaning "to gather, speak, or account".
The term "truth" originates from the Old English word "treowth", which signifies "faithfulness" or "truthfulness". It can be linked to the Proto-Germanic word "trewa" and the Old Norse word "tryggð", both conveying the ideas of "fidelity" or "loyalty".
When combined, "logical truth" refers to a statement or proposition that is true based on reason and logical inference. The etymology of this expression, therefore, combines elements related to reasoning, intellect, and fidelity to truth.
