Final answer:
Cicero, the noted Roman orator, believed people had responsibilities to society including cooperation, respect, and participation in governance. He encouraged a mix of altruism and self-interest for the community's good, and successful diplomacy was thought to strengthen society and lead to its success. Community responsibilities are essential for societal harmony and individual fulfillment.
Step-by-step explanation:
The great Roman orator referred to in this context is likely Cicero, known for his contributions to Roman politics and philosophy. Cicero believed that citizens had responsibilities towards their society, which included cooperation, respect, and civic engagement. He advocated for the idea that in a Politeia, or ideal society, the government serves the public good, allowing society to fulfill the true human potential of its citizens. This is achieved by exercising rational debate and discussion for the community's good, which implies a level of altruism.
Successful diplomacy, according to Roman beliefs, would strengthen the society and lead to the overall happiness and success of the state, much like in Plato's concept of the just city where each individual works for the greater good.
Finally, community responsibilities go beyond individual interests; instead, they involve sharing common beliefs about societal order and the treatment of others. Community responsibilities are the duties individuals owe to their community, ensuring their continued membership and overall societal harmony.
