1. IDEA 1 OF 8

   Effective altruism seeks the most good

   Singer describes effective altruism, a movement of people who try to do the most good they can with their time and money.

   Instead of giving based only on feelings, they use evidence and reason to choose how to help.

2. IDEA 2 OF 8

   Some earn more to give more

   Singer describes people who choose high-paying careers so they can donate much of their income.

   This approach, called earning to give, can sometimes do more good than working directly for a charity.

3. IDEA 3 OF 8

   Charities differ hugely in impact

   Singer explains that some charities achieve far more good per rupee or dollar than others.

   Effective altruists compare costs and results to find the most effective ways to help. Results should guide giving.

4. IDEA 4 OF 8

   Causes can be compared

   Singer argues that we can compare different causes, such as global health, animal welfare and reducing risks to humanity.

   Although difficult, comparison helps people choose wisely. Choosing among causes is unavoidable.

5. IDEA 5 OF 8

   Generous people live modestly

   Singer describes effective altruists who live simply so they can give more.

   Many find satisfaction in this choice. They see generosity as a source of joy rather than a sacrifice.

6. IDEA 6 OF 8

   Some give a kidney

   Singer describes people who donate a kidney to a stranger, accepting a small personal risk to save a life.

   He presents this as an example of extraordinary altruism. Their choices are rare.

7. IDEA 7 OF 8

   Reason guides compassion

   Singer argues that effective altruism combines compassion with reason.

   Feelings motivate us to help, but reason shows us how to help best. Both head and heart are needed. Each has a role.

8. IDEA 8 OF 8

   Doing good can be fulfilling

   Singer suggests that effective altruists often find their lives more meaningful.

   Helping others effectively can bring a sense of purpose. Many effective altruists say they are happier because of how they live.
