If filters are working right, they get dirty. I swapped out the furnace filters in the house today. They were dirty. So that was good.
In life filters can be good and they can be bad. Filtering certain shows from your young children is good. Filtering Internet access for an entire country is bad.
I suppose our minds have filters. We filter things coming in and things going out. Some are conscious and some are subconscious. Filters slowly put in place over time. From childhood, from school, from work, from society, from politics.
Don’t swear in front of children. Don’t be persuaded by communist ideals. Don’t go swimming right after you eat. You get the idea.
Filters are about don’ts. Don’t let this in. Don’t let that out. They are intended as protective measure I suppose.
But just like my furnace filter they start to collect lots of stuff. Unlike my furnace filter the filter in my mind continues to become denser as I add more and more to it as I learn about the world and myself. The filter becomes finer and finer. I am filtering more and more and the interaction between the different filters becomes more complex and actually starts filtering things I am not even aware of or ever intended. As if instead of replacing the furnace filter, I just put another over the top. Pretty soon almost no air is getting through. My filters are starving me of new ideas and knowledge.
I know my mind filter now contains ideas that are really no longer necessary and many that I no longer even find to be true. It’s so dense it’s casting a shadow on my mind. I don’t like that. I need air. Someone open a window. My filter has become a problem.
It’s time to replace my mind filter, let the light back in. It’s time to question the filters in place. If they don’t fit with who I think I am today, the filter needs to go. This is why great thinkers tell us to question everything. And to keep doing it. The questioning should not ever stop. Questions get rid of old filters and add new.
So as the barbarians at Capital One might ask, what’s in your filter?
