Purpose. In the classic discourse, the purpose becomes a brief mention of the general thesis the author wishes to propel. This is usually presented in the first few paragraphs of the essay. The following are some examples:
I will attempt to show how the social development and current human conduct aren’t achievements of our day and age, but rather, have issued from past events; this knowledge is a progression of ideas and actions that have been mended and transmitted through the years. (J. Jaramillo. The Human Adventure).
It is worth mentioning that this essay attempts to demonstrate the decisive role, along with endogenous factors of change, that have played in the exogeny as a result of the rapid insertion of this country in the global market, starting from the 1840s. (J. L. Vega. “Stages and processes of the sociopolitical evolution of Costa Rica”).
