Truth is typically understood as the correspondence between statements or beliefs and objective reality. In other words, something is considered true if it accurately represents the way things are in the world. It is the quality of being in accordance with facts, actuality, or reality.
However, discussions on truth can become complex when considering different philosophical perspectives. Some theories of truth include the correspondence theory (already mentioned), coherence theory, pragmatic theory, and deflationary theory, among others. Each of these approaches offers a slightly different perspective on what constitutes truth.
Regarding whether everyone's definition of truth is different, it's a matter of philosophical debate. Some people argue that truth is subjective and that each individual's beliefs and perspectives shape their understanding of reality. This view is more prevalent in relativism and some postmodern philosophies.
On the other hand, there are those who believe in objective truth, suggesting that there are facts and reality that exist independently of our beliefs or perspectives. In this perspective, people's perceptions or beliefs may vary, but there is still an ultimate truth that exists outside of individual interpretations.
It's worth noting that even if there is an objective truth, accessing or comprehending it can be challenging due to human limitations, biases, and the complexity of reality. Therefore, while the truth may exist independently, people's understanding and interpretation of it can indeed differ based on their perspectives, experiences, cultural backgrounds, and beliefs.
