How is truth different from opinion?
The truth is different from opinions because it is something that can be proven empirically. An opinion is something that can never be proven.
For example, we can clearly say that the truth is that New York City has the largest population of any city in the United States. This is a statement that can readily be proven. The number of people who live in each city in the United States can be counted, thereby telling us which city has the most people living in it. Since the census tells us that New York has many more people than any other city, we know that our statement is true.
By contrast, let us look at the idea that New York City is the most important city in America. This is a matter of opinion. There is no way to define “most important” in an objective and measurable way. We can measure how many people work in New York City and what the city’s “gross domestic product” is, but that does not tell us if it is the most “important” city in the country.
Truth can be proven. Opinions cannot be proven right or wrong.
