Well, from Wikipedia, although there are disagreements, Howard Gardner defines intelligence to encompass the following:
"Linguistic Intelligence, logical-mathematics intelligence, spatial intelligence, music intelligence, Bodily-kinesthetic intelligence (The ability to solve problems or to fashion products using one's whole body, or parts of the body. For example, dancers, athletes, surgeons, craftspeople, etc.), Interpersonal intelligence: The ability to see things from the perspective of others, or to understand people in the sense of empathy. Strong interpersonal intelligence would be an asset in those who are teachers, politicians, clinicians, religious leaders, etc. intrapersonal intelligence: A correlative ability, turned inward. It is a capacity to form an accurate, veridical model of oneself and to be able to use that model to operate effectively in life.
....Intelligence has been defined in many different ways including logic, abstract thought, understanding, self-awareness, communication, learning, having emotional knowledge, retaining, planning, problem solving... to adapt effectively to the environment, to learn from experience, to engage in various forms of reasoning, to overcome obstacles by taking thought."
Although ideas about what constitutes intelligence may vary from person to person, they share one thing in common: They were discovered by observing animals, and in particular, humans. Our whole concept of "what is intelligence" is basically based on our insights and understanding of how the human mind operates, solves problems etc.
To break it down further, our ideas about what defines intelligence are mainly anthropocentric.
So for the mean time, our understanding of the universe is constrained by the human mind. With genetic engineering and artificial intelligence we may discover new ways to define intelligence that we can't conceive of or even comprehend now. We may discover new & better ways to analyze the universe besides language & mathematics.
