In the name of “critical thinking,” I have noticed a tendency in the West for intellectuals to become not only reflective and deconstructive, but to frequently live in mentally aggressive/hostile, cynical, pessimistic, etc. states of mind. Although I would agree that being overly positive can bias one in various ways (e.g., to see only what you want to see and miss/ignore challenges, obstacles, etc.), being overly negative can bias one in opposite ways (e.g., to see only obstacles or challenges and miss/ignore what might be possible). So I think it is important to turn critical thinking against itself, and to be critical of becoming too negative of a person. To me, the main value of critical thinking is to acknowledge and let go of biases and assumptions, to become mentally detached and aware, to try to see and think clearly. Mental detachment is perhaps the primary activity/aspect of mindfulness meditation, as is awareness of vipassana meditation.
Many times in my life, in myself and others, I have seen how inaccurate, incomplete, often negative views can be reinforced by brooding or brainwashing — by a person going into some kind of echo chamber (in their head, on the Internet, only spending time with similar people in the real world, etc.) for a long time and repeating certain thoughts or feelings over and over until they become more and more extreme. The same was apparently true in the Buddha’s time, about 2,600 years ago: “‘He insulted me, he hit me, he beat me, he robbed me’ — anger will never cease in those who dwell on such thoughts” (Dhammapada, 3).
But real people are small and complicated. Everyone finds themselves born into a certain body, family, country, etc., which can be hard to escape. Everyone has had many unique past experiences that informed them. No one can see or learn everything. The only way to understand the complexity of life or people is to get out of your comfort zone (either mentally or physically) and have strange, new, different experiences. Brooding or brainwashing in isolation usually only makes one’s views more xenophobic, unrealistic, inaccurate, and incomplete; having difficult, new conversations and experiences usually makes one’s views more connected, realistic, accurate, and complete.
Here is a nice Ted talk, which says pretty much the same thing:
If karma is intention, how is it karmically pure to intentionally allow others to do your dirty work for you (e.g., to kill or be selfish to obtain your food or money, to kill people or steal things to defend your home or country, to kill germs or bugs in your home or office, to raise children so you don’t have to, etc.)? Aren’t you intentionally neglecting what is karmically best for the person who is serving you?
Similarly, even if someone didn’t intend to do a particular act of violence (e.g., to hit someone with their car), mustn’t there have been a intentional decision/willingness to create the circumstances that might give rise to that particular act of violence (e.g., to drive a car instead of taking another mode of transportation, to drive too fast, not to pay very close attention to the road, etc.)?
Some might argue that the act of generosity in serving another person cancels-out the impurity of the bad action, but the early Buddhist seed-and-fruit metaphor seems to say that each karmic seed bears one karmic fruit, meaning that both the bad deed and the good deed will bear separate fruits.
