It's about searching for the truth, not because somebody says it's true, "because I say so." No, it's about trying to find the truth based on what you can see and what can be tested.
Se trata de averiguar la verdad, no porque alguien diga que es verdad, "porque lo digo yo". No, se trata de averiguar la verdad basada en lo que se puede ver y comprobar.
