Terrorism Management Theory (TMT) asserts that human beings have a natural tendency toward self-preservation if their well-being is threatened (Greenberg, Solomon and Pyszczynski, 1997). He notes that we are the cultural animals that posit self-awareness on the concept of past and future, as well as the understanding that one day we will die. We are concerned about our life and death, but we are aware that everything is unexpected. The worst part is that we become aware of our vulnerability and helplessness when faced with thoughts related to death and ultimate disappearance (Pyszczynski and Greenberg, 1992). The inevitable awareness of death or the importance of mortality provides a ground for experiencing existential terror, which is the major concern of mortality and people's existence. To avoid the continued existence of threats, people need to believe in a relatively affirmative and plausive cultural worldview and meaning of life (Greenberg, Pyszczynski, & Solomon, 1995). Cultural worldview is a perceptual construct in society that explains the origins of life and the existence of the afterlife. We must invest ourselves in a set of cultural worldviews that can give meaning, stability, and order to our lives and offer the promise of transcendence of death (Solomon, Greenberg, & Pyszczynski, 2004) . On the other hand, we believe in living up to the standards of value prescribed by that worldview and social norm shared by a group of people. This belief arises from the individual's self-esteem. We maintain the perception and confidence that we fulfill cultural prescriptions of value in society and are therefore eligible for some form of personal immortality (Landau & Greenberg, 2006). We are associated with the hypothesis...... middle of paper ... and the accessibility to thoughts of death that are typically evoked by mortality reminders (Greenberg et al., 1993). Research has further indicated that self-esteem and death awareness are highly interdependent on each other and on the self-esteem and anxiety hypothesis. For the TMT, a second line of support for the terror management function of self-esteem comes from tests of the mortality salience hypothesis, which is another hypothesis derived from the TMT. Similar to the anxiety buffer hypothesis, it states that temporarily increasing the accessibility of death-related self-esteem provides protection against mortality concerns and that, therefore, individuals will then intensify their efforts to strengthen and defend their self-esteem. In summary, converging evidence supports the assertion that self-esteem functions as a buffer against mortality concerns (Pyszczynski, Greenberg, Solomon, & Maxfield)., 2006).
