Firstly, I shall define nature as the defining characteristics of a person or thing, and I shall focus on personality rather than physical characteristics. From this definition, the nature of human beings includes both shared and unique features. Shared features make every human similar and may be grouped into motivation, emotional expression and well as cognition. These concepts have been taken from the study of Psychology, the backbone of my academic background and therefore the basis of my conceptualization of the humankind. Nature as a model for consciously expressing individuality in personality may also be examined through motivation and emotional expression. Motivation drives behaviour and may be linked to needs, morality and culture. Perhaps the most influential theory of motivation is based on Maslow’s hierarchy of needs. According to this theory people are motivated to act in accordance to their needs which are arranged in a hierarchy with the most basic needs, physiological needs, at the bottom, and the highest-level need being self-actualization at the top. The lower order needs must be satisfied before the next higher need becomes a motivator. In addition to needs, morality can also be a motivator for behaviour and one theory, Kohlberg identified three levels of morality, namely pre-conventional, conventional and post-conventional morality. According to Kohlberg, people reason out their behaviours according to the depth of their internalization of social values. Furthermore, social values are greatly shaped by culture. Culture in a broad sense refers to how people live is manifested through of religion, language, dress and food. Moreover, many factors shape culture including geographical location, historical era and anthropological considerations. Although emotional expressions are universal across cultures, they are not always clear cut. A smile may be a universal indicator of happiness and a frown a universal indicator of sadness, however, an event that may cause sadness in one culture may cause happiness in another. Death may be cause sadness and yet it many cultures, yet for some it may be perceived as an end of earthly existence and freedom for other cultures. As a consequence, a funeral may be sombre for one family but cause for celebration in another. Additionally, although death may be associated with mourning, for a family that watched their loved one suffer through illness, that family may feel a sense of relief. Despite the universality of emotional expressions, there are individual differences on expressions across cultures and even within cultures.
