 Regarding, finally, those things which citizens are supposed to know and do in accordance with their respective classes (referred to as  b.i and b.ii above,  first paragraph of this section), al-Farabi seems to think of the various trades and professions performed in the  polis.[14]  As the next section will reveal, he differentiates between the individual skills and weaknesses with which each human being is born. He is convinced that, equipped with these specific talents, each human being possesses her natural place and duty within society. Actualizing her individual potential to the best of her capacities, hence, contributes to the functioning and well-being of the community. This, in fact, does not immediately lead towards individual happiness, but is a necessary precondition as it contributes to covering the daily needs and, thus, warranting the basis for society to aspire for its own natural telos (see  section 1  above).
