Ethics in the Real World: 82 Brief Essays on Things That Matter is a collection of short essays written over many years, and arranged by theme. In them, the author addresses politics, altruism, animal liberation, science, and many other topics, and is never afraid to share strong opinions, forcefully argued, or to diverge from his overall liberal stance. Reading sequentially can be annoying at times as some essays overlap, and practical solutions of perfectly good ideas are dismissed too lightly in my opinion. Yes, we can put a man on the moon, but it’s really a very simple project (even using 1960’s technology) compared to creating a universal public library. Still, one would wish that this more elevated type of thinking would permeate society instead of slogans and promises for quick fixes.
