It is important to always be in search of the truth.
Even if the truth is less pleasant than what you already believe. Even if the truth makes you change your entire structure of thought and your whole worldview on a subject. Even if the truth hurts your feelings. Even if the truth scares you. Even if the truth seems contrary to everything you’ve been taught. Even if the truth is controversial or radical.
There are some matters in which we might never find the truth. There are many things in which the truth will seem to be one thing, and with new evidence and searching, we find that it is another. Still, we cannot stop searching. Still, we cannot accept what we know now as fact — still, we must find more data.
In some cases, finding more truth may not change the way we behave, the way we interact with the world, or in any practical way change our lives. Take fuchsia, for example. When you learn the colors at a young age (particularly if you were like me and had the 100+ color crayon box), you learn that fuchsia is this vivid purple/pink/reddish hue that you might call “highlighter pink” or something. The color is named after the Fuchsia plant genus which typically portrays that vibrant pink color. You knew that fuchsia was a color, you could identify it out of the crayon box, and you learned how to spell it — you maybe even knew where the name came from. The color fuchsia was a truth to you. Then you learned, some 10-ish years later (or maybe you’re learning this today, how neat!), that the color fuchsia doesn’t exist. On the color spectrum, there is no combination of purple and red; in fact, violet and red are on opposite sides of the visible light spectrum with their wavelengths (violet at ~400nm and red at ~700) And yet, we see the color fuchsia (and magenta, and red-violet, and all kinds of other crayons that fall between the “violet” and the “red” when you sort them in the box by color). What is happening with these colors is that our brain is just taking a wild guess about what the color would be — which, to be fair, is exactly the same thing our brain is doing with 99% of all colors all of the time — and our brain invents this new color which mushes purple and red together and forms a sort of loop with the color spectrum, when really it’s just a line.
Now, does learning this new fact about the color fuchsia change the way you are going to get up and start your day? I imagine not. However, is it still important to continue searching for more truths and compile more evidence about the way that we perceive the world around us, and the way our brain calculates visual stimuli? Certainly.
In other cases, finding more truth may shake you to your core. It may rattle everything you feel you have ever known. It may make you question your reality. This is a good thing. You should be questioning your reality, constantly. You should be questioning your beliefs, your strongly-held feelings, and your deeply-ingrained teachings. If you come back from searching and questioning with the same evidence-supported beliefs as you had before, good. If you come back with new information that makes you change your views, better. If you come back with even more questions and maybe a little bit of uncertainty about what actually is true, fantastic. Never stop, and never settle for anything less than the truth. Then search some more, just in case that wasn’t actually the truth after all.
