If you are not prepared to resign or be fired for what you believe in, then you are not a worker, let alone a professional. You are a slave. - Howard Gardner

When Einstein had thought through a problem, he always found it necessary to formulate this subject in as many different ways as possible and to present it so that it would be comprehensible to people accustomed to different modes of thought and with different educational preparations.

Narrative: telling stories about the topic and the people involved with it (e.g., the story of Charles Darwin for evolution or of Anne Frank for the Holocaust) 2. Quantitative: using examples connected to the topic (e.g., the puzzle of different numbers and varieties of finches spread across a dozen islands in the Galapagos) 3. Logic: identifying the key elements or units and exploring their logical connections (e.g., how Malthus’s argument about human survival in the face of insufficient resources can be applied to competition among biological species) 4. Existential: addressing big questions, such as the nature of truth or beauty, life and death 5. Aesthetic: examining instances in terms of their artistic properties or capturing the examples themselves in works of art (e.g., observing the diverse shapes of the beaks of finches; analyzing the expressive elements in the trio) 6. Hands-on: working directly with tangible examples (e.g., performing the Figaro trio, breeding fruit flies to observe how traits change over the generations) 7. Cooperative or social: engaging in projects with others where each makes a distinctive contribution to successful execution

"Berlin suggests that "in the case of seminal discoveries-say of imaginary numbers, or non-Euclidean geometry, or the quantum theory- it is precisely dissociation of categories indispensable to normal human experience, that seems to be required, namely a gift of conceiving of what cannot in principle be imagined nor expressed in ordinary language." Like Newton and Copernicus, Einstein sustained a vision of a unified, harmonious, physically caused world. This dissociation led both to Einstein's genius in the world of physics and his inspirational, but ultimately less successful, forays into issues of world order."
