Answer:

A little knowledge is a dangerous thing

The proverb 'A little knowledge is a dangerous thing' means that gaining a little knowledge can be dangerous if we fool ourselves into acting like experienced experts. Overconfidence and pride can lead us to making serious mistakes which we will regret later. When we do things with proper knowledge it minimises the risk and danger to ourselves and to other people. For example, large and long bridges or tall buildings built by an engineer with inadequate knowledge will collapse sooner or later.

A man with deep knowledge is humble and does not indulg­e in cheap publicity. He will be known by the high quality of his works. But a man of shallow knowledge always try to show off to impress other people. He proclaims himself to be an expert. Such a man causes great harms to the society.

This proverb warns us not to become falsely overconfident when we merely possess a small amount of knowledge about a subject. We should study and research on a topic extensively before proclaiming ourselves as experts and professionals.
