Augustine’s Two Cities and Plato’s Cave: Exploring History and Knowledge

Philosophy of History

Christianity posits that mankind, united in the first man, disobeyed God. Since then, humanity has been caught in a struggle between two loves: love of God (amor Dei) and love of self (amor sui).

Tourism in Spain: Economic and Cultural Benefits

In my opinion, yes. Because in our country there are many beaches and monuments, plenty to see, and tourism revenues are much in our favor because it gives us lots of money. Besides, tourism employs many people because they expand hotels and bars. With more tourism, we also learn from the culture of those who come, such as their language, so they feel more comfortable and want to return. In short, I believe that it is important to attract tourists
