Newton is arguably one of the greatest scientists in the world, and he has achieved countless achievements in his lifetime, receiving unprecedented praise. But no one is perfect, and Newton, who has great wisdom, is still a lonely person until he dies. Why, then, did Newton not marry for the rest of his life?
First, let's start with Newton's family. Newton was born on 4 January 1643 to a farming family in the small town of Walsop, Lincolnshire, England. He was a widow and premature baby, weighing only three pounds at birth.
When he was two years old, his mother remarried to a priest, and at the age of 11, her mother returned to Newton. Newton was reticent and stubborn, even weird, and difficult to get along with.
From about the age of 5, Newton was sent to public school. He has average grades, but loves to read books, likes to read books that introduce various simple mechanical model making methods, and is full of curiosity about natural phenomena. He also likes to do small tools, small inventions, and small experiments.
In 1661, at the age of 19, Newton entered Trinity College, Cambridge, as a fee-reducing student, and paid for his tuition on the income from doing chores for the college, becoming a scholarship recipient in 1664 and a bachelor's degree in 1665.
From 1665 to 1666, a severe plague swept through London, and schools were closed. Newton left school in June 1665 and returned home. The short period from 1665 to 1666 became the golden age of Newton's scientific career, and he rose to prominence in the field of natural sciences, thinking about problems that had never been thought of before, and creating unprecedented and amazing achievements. During this time, for the first time, he fell in love with a beautiful, intelligent, studious, thoughtful cousin. My cousin also liked this knowledgeable and knowledgeable college student. But when Newton returned to Cambridge, he was completely immersed in scientific research. He had long forgotten his distant cousin, who mistakenly thought that Newton had no intention of her, so he chose a husband and married her. Newton's obsession with scientific research missed the opportunity for love.
Newton was immersed in his own world all day, full of only his own work and study. He didn't trim all day and dressed scruffily. Nevertheless, Newton was a young man after all, and once the "passion of youth" led him to propose to a young girl. But when he dated the girl, he was so distracted for some reason that he used his lover's finger as a pipe stick and forced it into the pipe. The girl screamed in pain before he woke up. Love has become a bubble again.

In addition to his obsession with science, Newton's character flaws also prevented him from gaining his love. He has been plagued by mania since he was a child and has a hard time getting along with people. In 1692, at the age of 50, Newton showed severe symptoms of persecution, and the letters he wrote at that time showed that he had become visibly insane.
On September 16, 1693, Newton wrote to the famous philosopher Locke: "Sir, I think that you have tried so hard to entangle me with women and other means, and my feelings have been so greatly affected that when someone tells me that you are sick and will not be able to live, I reply, it is better that you die." This state of mind can no longer allow him to look for his other half in his old age.
In addition, the influence of teachers is also one of the reasons. Newton's geometric optics teacher, Bello, was a very good teacher, and Newton liked him very much, and he also regarded Newton as his own son, and this teacher had a nearly identical childhood with Newton, and he was never married. Newton may have been influenced by his teachers to become indifferent to his attitude toward marriage.
Of course, lifetime unmarriage was and is too common in Europe, according to the data, during the time of James IV in the United Kingdom, the unmarried rate of all women over 50 years old in The United Kingdom was 25%, and the unmarried rate of men over 50 years old was almost 20%; in the Victorian era, the unmarried rate fell to about 20%, and after the Industrial Revolution, it rose again, but always maintained an unmarried rate of about 25% of the population over 50 years old. Therefore, in Britain, it is not unusual for Newton to be unmarried for life.
