It is regrettable that those with the best genes - the ones of intelligence - are usually excluded from society's gene pool. There are two reasons for this, the very simple, the simple and the one that will blow your mind.
The very simple reason is you can't think about math, you can't read the classics, you can't learn science, when you're doing drugs and having orgies all the time.
The simple reason to understand is the biological relation between offspring and intelligence. See, living beings like bugs lay thousands of eggs, fish lay hundreds, cats and dogs have 5 individual offsprings, niggers have 4, whites and asians have 2 or 1, and so the most intelligent, evolved and superior of all naturally have no children.
The one that will blow your mind is that intelligent people do not need to reproduce because they can pass on information through means other than DNA. See, all living beings pass on information - even after they die -. They do so, usually, with DNA. The thing with DNA is that it's within a cell, it's information that exists within the living being. Humans, however, differ from animals in that they can pass some information without DNA, and thus, beyond their own inner mechanisms. Humans do this by, for example, writing books, playing music or engineering technologies. We can use the environment to pass on information. And that's why the phenomenon of smart ones like monks and scientists being socially excluded is so common. They don't have a biological necessity to breed, to have kids, to pass on their DNA, when they can pass on information by means like active research, publishing an article or writing a book.
This is why the greatest humans of all - Jesus, Buddha, Newton, Tesla, Beethoven, etc - are all virgins.
