The Manosphere delusion is that women lack empathy because of "solipsism." The first problem with that is "solipsism" is a philosophical problem, not a psychological one. The word is used incorrectly. Not a little incorrectly, but completely.
The second problem is that even if women are "solipsistic," it explains nothing. "They lack empathy because they're solipsistic." What does that even mean? Nothing. It's gobbledegook.
Women are less empathic than men because they lack imagination, and imagination is how you put yourself in someone else's place.
Adam Smith, in 1759, wrote a book called The Theory of Moral Sentiments, in which he suggested that imagination is what creates empathy. I have a book, The Creative Imagination, about the arguments during that time about the relationships between imagination, creativity, religion,science, art, morals and empathy. It's a big book.
Look at history. Who created everything? Men. For all practical purposes, a very small number of imaginative, creative men.
Consider Nickolai Tesla. This is what he wrote about his imagination:
“I soon discovered that my best comfort was attained if I simply went on in my vision further and further, getting new impressions all the time, and so I began to travel; of course, in my mind. Every night, (and sometimes during the day), when alone, I would start on my journeys – see new places, cities and countries; live there, meet people and make friendship and acquaintances…
"This I did constantly until I was about seventeen, when my thoughts turned seriously to invention. Then I observed to my delight that I could visualize with the greatest facility. I need no models, drawings or experiments. I could picture them all as real in my mind… I do not rush into actual work. When I get an idea, I start at once building it up in my imagination. I change the construction, make improvements and operate the device in my mind."
I understand the power of imagination. Between 12 and 14 I used to get lost in a book. It was more real than reality. At first I didn't understand why everyone wasn't like me, but I was fast disabused of that notion by encountering the stupid and unimaginative. I was shocked at that for a long time and considered them no better than Morlocks.
I do know this, though: women, except a select few (and they are outliers) have created nothing. Why? No imagination. No creativity.
Why this is so I do not know. But it's true. It's also a bit scary.
