Heather (https://twitter.com/zoophilosophy & https://www.heatherbrowning.net/) is a scientist, philosopher & a former zookeeper & welfare officer. She is now a researcher at the London School of Economics specialising in animal sentience, welfare, & ethics. 
In Sentientist Conversations we talk about the two most important questions: “what’s real?” & “what matters?” Sentientism is "evidence, reason & compassion for all sentient beings." The video of our conversation is here on the Sentientism YouTube.
We discuss:
1:33 Heather Intro - biology to zookeeping to philosophy
- Volunteering, later working at zoos. Getting to know animals
- Studying zoology/biology
- Studying philosophy, shifting to PhD focus on measuring animal welfare
- "Cheetahs don't really like to run"
- How do "natural behaviours" relate to animal welfare
- Trying to take the animal's point of view
- The Foundations of Animal Sentience programme at LSE
- The power of interdisciplinary work

10:55 What's real?
- Growing up in a fairly naturalistic household. Occasional church visits
- Being encouraged to question & explore
- Joining a church group for the community
- Balking at religious rules/restrictions
- Asking questions & not getting answers
- "Science just seemed like the best way of investigating the world"
- Scientists are flawed humans too
- There are many things we don't know & some we may never understand
- We're evolved creatures that have developed heuristics that have been useful to us for survival/procreation
- The dangers of a need for/expectation of perfection
- Dangers of over-confidence/dogma/motivated reasoning in science

21:54 What matters morally?
- Naturalism does involve giving up meaning, but we can create our own meaning
- Hedonist nihilism. What matters to me?
- Sitting between naturalising or eliminating morality, vs. moral realism
- Evolutionary basis of human consciousness, including empathy, fairness, co-operation (and not just in humans)
- "What matters is the subjective pleasure and pains we have in our lives"
- "Our wellbeing is an objective fact about the world"
- Empathy is caring about the wellbeing of others

31:42 Which entities matter? Moral scope
- "I've always loved animals"
- At 5 yrs "When I grow up I want to be a zookeeper"
- Finding it difficult to eat meat. Feeling disgust 
- Saying "I'm vegetarian" to get out of cooking meat in a class, then realising "I could just do that" and going vegetarian at 12 yrs
- Supportive parents: "Now you need to learn to cook!" & being joined by a sister
- A friend was told "You can't go vegetarian"
- And much more... See Sentientism.info or YouTube for full notes.
