They experience this intense caring most often in their relationships with others but they may also experience it around ideas, projects, or any involvement they see as important. INFPs are often skilled communicators and are naturally drawn to ideas that embody a concern for human potential. INFPs live in the inner world of values and ideals, but what people often first encounter with the INFP in the outer world is their adaptability and concern for possibilities.”*

“For INTPs the driving force in their lives is to understand whatever phenomenon is the focus of their attention. They want to make sense of the world —as a concept—and they often enjoy opportunities to be creative. INTPs are logical, analytical, and detached in their approach to the world; they naturally question and critique ideas and events as they strive for understanding. INTPs usually have little need to control the outer world, or to bring order to it, and they often appear very flexible and adaptable in their lifestyle.”*
My religion professor in college, Dr. Bernard Boyd, was one of the most colorful people I have ever known. The wonderful stories he told brought his teachings to life in a way his students would have never believed possible. One of his best was about Albert Einstein.
While young Boyd was a seminary student at Princeton, Dr. Einstein was a professor there, well-known for his absent-minded ways. On more than one occasion, Boyd saw the famous theoretician and scientist wandering aimlessly in the middle of the street licking an ice cream cone, totally oblivious to traffic and the potential threat to his life.
One day, late for a class, Boyd was rushing down the library steps and accidentally bumped into Dr. Einstein, almost knocking the two of them down. Stunned, he realized who it was and hurriedly apologized. Einstein was polite and said not to worry about it. What happened next was a complete surprise. The almost-speechless Boyd suddenly blathered, “Why don’t you come to my room tonight around 8 and meet some of my friends.” Einstein said that sounded like fun, and promised he’d be there.
Boyd spent the rest of the day telling all his friends to come by his room that evening because “Big Al” was going to be there. When they asked, “Who’s Big Al?” he responded vaguely, “It’ll be fun. Just come.” So they did. A small crowd gathered in anticipation of meeting Big Al, who, as almost always, was late.
Around 8:20 a few people were starting to leave, when suddenly Albert Einstein appeared and asked for Bernard Boyd. At first some of the friends thought the man was an impostor, even a hired prankster, but they soon realized it really was Albert Einstein in the flesh.
Dr. Boyd related that Albert Einstein was colorful, lively, and very friendly, answered lots of questions and participated in a “bull session” so typical of anyone’s college days.
A few years later, Einstein passed away and gave humanity and science one last great lesson. Einstein had always been widely regarded as one of the greatest minds on the planet, if not the greatest of all time. Scientists had a special curiosity to study his brain after his death, so he granted their wish—under one condition. He handed the scientists a sealed envelope with specific instructions that the contents be read only after the scientists finished their research, which took place at Cornell University.
After weeks of intensive study of his brain and much debate among the scientists, they called a press conference to present their findings. They had indeed uncovered a major difference between Einstein’s brain and everyone else’s, but it was not the difference anyone had expected. Einstein’s brain was about three-fourths the size of a normal human adult’s. Other than that, there was absolutely no discernible distinction.
Following that incredible press announcement, the sealed envelope was opened to reveal a single sentence. It read, “I do not consider myself to be especially smarter than any other human, but I do have a particularly vivid imagination.”
“Our only limits are in our imagination.” —Albert Einstein

“For INFJs the dominant quality in their lives is their attention to the inner world of possibilities, ideas, and symbols. Knowing by way of insight is paramount for INFJs, and they often manifest a deep concern for people and relationships as well. INFJs often have deep interests in creative expression as well as issues of spirituality and human development. While the energy and attention of INFJs are naturally drawn to the inner world of ideas and insights, what people often first encounter with INFJs is their drive for closure and for the application of their ideas to people’s concerns.”*

“I have such a rich spiritual life. Most people take drugs to experience that. I’ve only smoked two joints in my life—once at the Grosvenor House in London and it made me so hungry I nearly ate the furniture—and the other time at a party near here. I stared at a TV test pattern for 14 hours. I don’t need drugs to have imaginative fantasies.” She points to a doormat on the balcony—Welcome UFOs and aliens—and says she doesn’t take herself too seriously. “How can I? I’m used to people thinking I’m wacky but what I’ve said for 30 years is now mainstream. I don’t feel I told you so. I’m prepared to be misunderstood. It’s taken me a long time and a lot of soul searching, but I’ve finally come to know who I am.” —Shirley MacLaine
