I watched an interview with Bertrand Russell from 1952. Almost at the end, the interviewer asks Russell about his view on Marx's philosophy. Here's how Russell responds.
I think one of the troubles of the world has been the habit of dogmatically believing something or other. And I think all of these matters are full of doubt, and the rational men will not be too sure that he is right. I think that we ought always to entertain our opinions with some measure of doubt. I shouldn't wish people dogmatically to believe any philosophy, not even mine. No, I think we should accept our philosophies with a measure of doubt.
Over seventy years later, things have gotten worse. Having doubts is seen as a sign of weakness, and communication, reduced to slogans and short messages on social media, has no room for doubts.
Yet, in my quest for truth, there are way more doubts than certainties.
Niels Bohr used to say, "If you are not puzzled by quantum physics, you couldn't possibly have understood it."
I would say it also applies to the truth.
If you are not puzzled by the truth, you couldn't possibly have understood it.
