This article explicates Spinoza’s terms of self-preservation1 as his philosophical view in his book “Ethics”2 (published in 1677), written in a geometrical method. Generally, self-preservation refers to attention on the needs or desires of an individual self. The term self-preservation is often used simply to denote the attitude of caring about one’s own good. It is a view that human beings are always motivated by self-preservation, which is a necessity view of life. Spinoza has a broader view of the term. He identified self-preservation as the ultimate aim and proper motive of morality. His philosophical view of self-preservation is a more enlightened self-preservation, which shows that acting for one's own self-preservation can also serve others. Spinoza emphasized that the concepts of good, virtue, into perfection, have a ground in every human being, whilst evil is a condition in which virtue in ordinary people is still in its early unfoldment. Ordinary individuals tend not to undergo rigorous life and therefore they become preys for their passive emotions. According to Spinoza: evil actions are the result of ignorance. Therefore, he emphasized that individuals good potentials must be developed. The higher the individual understanding is, the more the individual has the power to propel himself from within, to enlighten himself, but also to help and bring happiness to others. He argued that an individual’s goodness will inspire others to achieve contenment. The difference of self-preservation term with other philosophical views of it can be observed through his propositions in his “Ethics”. Spinoza’s understanding of the importance of self-preservation, by improving one’s rational ability, is an exclusive view in his era, and can still be an inspiration to individuals today.
