"در واقع دو چیز وجود دارد ، علم و نظر؛ اولی دانش ایجاد می کند ، دومی جهل."

Science and opinion are two fundamentally different things. Science is based on facts, experiments, and evidence. Opinion, on the other hand, comes from personal beliefs, feelings, or assumptions. When you think about it, science leads to real knowledge—things we can test and prove. Opinions, however, can sometimes lead us astray. They’re not always backed up by solid evidence, and following them blindly can sometimes make us more ignorant instead of informed.

This idea comes from a long history of valuing evidence and the scientific method. Think back to ancient Greece. Philosophers like Aristotle began formalizing methods for gathering and testing knowledge. They realized that just believing in something because it felt right wasn't enough. You needed to test, observe, and gather evidence. That's the spirit of this quote.

Now, let's look at a real-life example. Imagine you’re trying to decide whether a new health supplement is effective. On one hand, you have scientific studies showing the supplement’s effects, tested in controlled trials. On the other hand, you have opinions—maybe from friends or online reviews. Science might show that the supplement works, but opinions can be all over the place. Some people might claim it's a miracle cure, while others say it did nothing for them. If you rely only on these opinions, you might end up confused or misled. But if you look at the science, you get a clearer picture based on real evidence.

So, how do you apply this wisdom in your own life? Start by questioning where your beliefs are coming from. Are they based on solid evidence, or are they just opinions? When faced with a decision, look for reliable sources and scientific evidence. You don’t have to ignore opinions altogether—they can offer valuable insights—but weigh them against proven facts. It’s like building a sturdy house: opinions are like the decorative elements, but science is the foundation.

Let's make this more relatable. Imagine you’re at a family dinner, and the topic of climate change comes up. Your uncle insists that it’s all a hoax, based on what he’s read on some blogs. Your cousin, however, cites scientific studies showing rising global temperatures and ice caps melting. Who do you believe? Here’s where you remember the core idea: science leads to knowledge, while opinion can lead to ignorance. You don’t outright dismiss your uncle’s view, but you weigh it against the solid evidence your cousin presents. You might even decide to look up more information later, from credible scientific sources.

In the end, it’s about being critical and thoughtful. Don’t just accept things at face value. Dig a little deeper. Ask questions. Seek out evidence. That way, you’re building your understanding on a solid foundation of knowledge, rather than shaky opinions. And that’s a smart way to navigate through the sea of information we all face every day.
