“The more the fruits of knowledge become accessible to men, the more widespread is the decline of religious belief.”

Simplified Meaning:

When more people have access to information and can learn new things easily, they start to believe less in religion. This is because learning helps people understand the world through facts, science, and evidence. For example, in history, many people believed that the Earth was the center of the universe because religious teachings said so. But when scientists like Galileo shared their discoveries that the Earth revolves around the sun, people began to see that religious explanations weren't always correct. As people learn more about science, nature, and the universe, they often rely less on faith and more on proven knowledge. This explains why, in societies with high education and access to information, there tends to be a decrease in religious beliefs. Learning and knowledge help people understand the natural world, reducing the mysteries that religions often try to explain.
