Jealous, adj. Unduly concerned about the preservation of that which can be lost only if not worth keeping.

In the quote "Jealous, adj. Unduly concerned about the preservation of that which can be lost only if not worth keeping," Ambrose Bierce offers a cynical and sharp critique of the emotion of jealousy. He suggests that jealousy arises when a person becomes excessively protective or anxious about something or someone that is not truly valuable or secure. According to Bierce, the very act of jealousy may signal that the object of desire or affection is not worth holding onto in the first place. If something can be easily lost, it may not be deserving of such intense attachment or fear of loss.

Bierce’s use of the word "unduly" emphasizes that jealousy often goes beyond reasonable concern and becomes an irrational fixation. This exaggerated concern reflects a lack of trust or insecurity, where the person feeling jealous is overly focused on preserving something that may not have true value or importance. The quote implies that jealousy stems from a fragile attachment, one that is driven by fear of losing something that is not inherently significant or secure.

The second part of the quote, "that which can be lost only if not worth keeping," further deepens Bierce’s critical view of jealousy. He argues that if something or someone can be easily lost, it is likely not worth the intense emotional investment that jealousy requires. This suggests that genuine relationships or valuable things are secure and do not require excessive jealousy to preserve them. In fact, trust and security are often what make something or someone truly worth keeping, not the fear of losing it.

Ultimately, Bierce’s definition of jealousy portrays it as a misguided and often destructive emotion, one that focuses on the preservation of things that may not deserve such attachment. His perspective highlights the absurdity of being consumed by jealousy over something that may be fleeting or unworthy of the emotional turmoil it causes.
