What is a concise statement that conveys a general truth or principle called?

A concise statement that conveys a general truth or principle is referred to as an aphorism. Aphorisms are often memorable and thought-provoking, expressing insights about life or human nature in a succinct manner. They are designed to resonate with readers, often encapsulating wisdom or moral lessons in just a few words.

Although the terms proverb, maxim, and adage all also refer to statements that express truths or morals, they can carry slightly different connotations. Provers often derive from traditional sayings and reflect cultural wisdom, whereas maxims are generally broader principles or rules of conduct. Adages typically possess a long history, being widely accepted over time. Aphorisms, in contrast, may be more original or philosophical in nature, emphasizing pithy expressions rather than relying on traditional frameworks. Thus, while all the terms relate closely, the unique qualities of an aphorism make it the most suitable choice for defining a concise statement that conveys a general truth.
