What is intelligence? Let us count the ways. Actually, the many definitions you’ll find below are merely the tip of the iceberg. I have listed my sources at the end of this post. “I’ve become more aware of and impressed by how much of leadership is about emotional intelligence. The more you lead, the more you understand how much of it is about motivation – and motivation is about emotions…To lead, being smart isn’t sufficient. You have to connect with people so that they want to help you move the organization forward.” Robert Joss, Dean of Stanford University’s Business School. “Knowing a great deal is not the same as being smart; intelligence is not information alone but also judgment, the manner in which information is collected and used.” Carl Sagan “I not only use all the brains that I have, but all that I can borrow.” Woodrow Wilson “It's not that I'm so smart, it's just that I stay with problems longer” Albert Einstein “Continuous effort - not strength or intelligence - is the key to unlocking our potential.” Winston Churchill “Intelligence is the ability to adapt to change.” Stephen Hawking "The capacity to acquire and apply knowledge, especially toward a purposeful goal." dictionary.com “We define emotional intelligence as the subset of social intelligence that involves the ability to monitor one's own and others' feelings and emotions, to discriminate among them and to use this information to guide one's thinking and actions.” Salovey & Mayer, Emotional Intelligence (1990) “Does a president need to be smarter than his advisors? The key is how to define ‘smart.’ A president can hardly be more expert than, in sum, a collection of advisors…” Ron Suskind, The Price of Loyalty "Much evidence testifies that people who are emotionally adept -- who know and manage their own feelings well, and who read and deal effectively with other people's feelings -- are at an advantage in any domain of life, whether romance and intimate relationships or picking up the unspoken rules that govern success in organizational politics.” Daniel Goleman “Intelligence is solving a problem or creating a product that is valued in society.” Image by Brunosan at Flickr (creative commons) Image by Brunosan at Flickr (creative commons) Howard Gardner
