To discuss the topic of "truth" is a very provocative subject, because everyone claims to be right. Religious fanatics, Catholic priests in their sermons, and other Christian preachers are the loudest in claiming to be right. Christian fanatics use the term "truth" significantly more than other philosophical schools of thought. Overall, dogmatic religions like Christianity and Islam use these concepts the most.
But when I had the opportunity to communicate with Christian fanatics about critical arguments about religion, they were all exactly the same: they were going to have a mental breakdown from the criticism of religion, they felt very hurt, offended, insulted, and irritated.
The biggest joke is that even Christians say about themselves that they are looking for the truth – well, if they were really sincere, they would have no problem subjecting their own religion to criticism and would even be grateful for the criticism, that it would enrich them.
Whether we are right in science can be checked and verified based on experiments. Take, for example, a passenger car: its production and operational functionality require dozens to hundreds of mathematical and physical formulas or procedures. If they were not true, we would not have a functional car.
In the world of philosophy, it's more complicated – here you can't check yourself to see if you're going in the right direction. (A side note: this is partly because psychology is one of the most backward and slowest-developing sciences).
