"唯一增强智力的办法是对任何事都不做决断，让思想成为所有思绪的通途。"

The core idea here is to basically keep your mind open and flexible. Instead of locking onto a single idea or belief, let your mind be a place where all sorts of thoughts can pass through freely. It’s like having an open door policy for your brain—letting a variety of ideas come and go, rather than sticking rigidly to one.

This idea has roots in the philosophical traditions of skepticism and open-mindedness. Historically, thinkers like Socrates and more modern philosophers like John Stuart Mill have stressed the importance of questioning everything and entertaining multiple viewpoints. By not settling on a single 'truth,' they believed you could better understand the world and strengthen your intellectual capabilities.

Imagine you’re working on a tough project at work. You’ve got to come up with a new marketing strategy for a product that’s not selling well. You could fixate on one approach—maybe you think social media is the way to go and you’re set on that. But what if you took another approach? What if you let all possible strategies flow through your mind, from traditional advertising to word-of-mouth campaigns to influencer partnerships? By not making up your mind too quickly, you give yourself the opportunity to explore all avenues. You might discover that a combination of several strategies is the best solution.

So how do you apply this in your own life? Start by consciously reminding yourself to stay open. When you catch yourself immediately agreeing or disagreeing with something, take a step back. Ask yourself, “What are the other perspectives here?” Dive into different sources of information. Read articles or books from authors with opposing viewpoints. Engage in conversations with people who have different opinions from yours. It’s a bit like mental exercise—the more you practice, the better you get at it.

Think about a time when you were absolutely sure about something—like, say, a movie you thought you’d hate. Let’s say your friends kept raving about it, but you just knew it wasn’t for you. Maybe it was a genre you didn’t like or a director you never cared for. But what if you finally decided to watch it, just to see what the fuss was about? Maybe you found elements in the movie that surprised you, or perhaps you even ended up loving it. That experience of shifting from a rigid belief to an open-minded discovery is exactly what the quote is advocating for.

By keeping our minds open, we enrich our understanding and foster intellectual growth. So next time you’re faced with a decision or a new piece of information, let your mind be that thoroughfare. Don’t rush to make up your mind. Let the variety of thoughts flow through, consider them, and see where they lead you. It’s a practice that can open up new possibilities and deepen your understanding in ways you might never have imagined.
