Self-quotation refers to the act of quoting oneself, either in written or spoken form. It is a literary device used by authors, speakers, and artists to emphasize their own words and ideas, often for the purpose of self-promotion or self-reflection. Self-quotation can also be seen as a form of self-referentiality, where an individual references their own previous work or statements. This can be done for various reasons, such as reinforcing a particular message, showcasing personal growth, or adding depth to a current piece of work. However, self-quotation can also be seen as a form of vanity or self-indulgence if used excessively. In the world of literature and art, self-quotation can be a powerful tool when used effectively, but it should be used with caution and intention.
