According to Bereshit (Book of Genesis), a man has an emotional need for validation that is different from a woman’s emotional need for validation.
According to Bereshit, God took some dirt (adamah), pushed it into the shape of a male human, breathed into it, and the male was brought to life. First there was dirt, then there was a living male person. This is called “yesh mi ayin”, something from nothing.
To make the female human, God put the living male to sleep, removed a part from his side, and fashioned it into the female person. The woman was created from something that was already a complete creation. This is called “yesh mi yesh”, something from something.
For this reason, Torah explains that a man is always trying to prove himself. Men know intuitively that they were created from dirt and feel that they are “something from nothing”. They feel insecure. By contrast, women do not have this drive to prove themselves because women understand that they were created “something from something”. We know intuitively that we are complete. In truth, every living person is worthwhile and precious, but men and women feel it differently.
I would add that it is a bitter pill for men to feel inadequate and a bitter pill for women to be unable to do anything about it. We do, after all, marry those men (sometimes) and end up in relationships with them. They bring their insecurity into the relationship. “And knowing is half the battle.” – G.I. Joe
