Insight denotes the knowing of oneself. This introspective prerequisite is fading away more and more everyday. Insight is more of an intutive ability. Meaning that it comes from the subconscious part of the mind. Often times insight is thought of as an ability or thing projected or granted to others but the truth is insight begins with knowing oneself.
“Outsight starts with insight without that knowledge outsight is limited and bigoted”
The ability to observe ones surroundings and learn from them is the foundation of true learning. But a reference point is always needed to gauge the new data. When a person understands his own deep processes, feelings and emotions, he is more likely to understand the processes of others more accurately. This process of thinking is commonly known as empathy.
“Empathy; the ability to understand and share the feelings of another.”
Most of a persons emotional processes are located in the subconscious, the ability to understand these calculations is a form of genius, self awareness or introspective genius, as noted by Howard Gardner in his nine classical forms of intelligence.
“Intelligence; is the ability to acquire and apply knowledge and skills”
So, for a person to have the ability of outsight he most first have insight. This self awareness well surely aid with interpersonal skills allowing him to gauge and calculate more accurately the thoughts and feelings of others.
