Scientists are supposed to study animals in a totally objective fashion, similar to the way we inspect a rock or measure the circumference of a tree trunk. Emotions are not to interfere with the assessment. The animal-rights movement capitalizes on this perception, depicting scientists as devoid of compassion.

To ask questions can become the laziest and wobbliest occupation of a mind, but when you must yourself answer the problem that you have posed, you will meditate your question with care and frame it with precision.

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.
