My thesis is a study on preservation: both the acts of preserving and not-preserving in different contexts: their intention, mechanism and consequences. From an individual's collection of a fragile stamp to the collective protection of an endangered species, the human need and desire for preservation always exists. The action of preservation reflects human’s effort to prevent things from changing, decaying, dying, or other unfavorable states resulting from not-preserving. However, preservation does not always lead to positive results. The act of not-preserving is just as significant as preserving, and this fact is often overlooked or simply negated. My work specifically dives into this dichotomy between preserving and not-preserving, aiming to uncover the fact that they are not mutually exclusive, to interrogate the traditional western philosophy of dualism, and to consider possibilities inhabited in alternatives: the potential to not-preserve.
