The Cave and the Question

In one line Zera Yacob, hiding in a cave, saw that each faith called itself true and turned to reason to decide.

Zera Yacob was born in Ethiopia in 1599. A teacher, he was caught up in religious conflict when the king favored Catholic missionaries. Accused before the king, he fled and lived for about two years in a cave. He later wrote down the thinking he did there in a work called the Hatata, which means inquiry. Scholars still argue over whether the text is his.

He noticed that Christians, Muslims and Jews each said their own faith was true and the others false. They could not all be right, and each side relied on its own tradition. So he decided to test claims by the light of reason, which God gives to every person.

He kept his belief in a creator, which he thought reason supports. But he judged doctrines and laws by whether they fit reason and the order of nature.

Go deeper

Zera Yacob’s Hatata, with a second one by his student Walda Heywat, came to European attention in the nineteenth century. In 1920 the Italian scholar Carlo Conti Rossini argued that both were forgeries by the Italian missionary Giusto d’Urbino. Later scholars, including Claude Sumner, defended their authenticity, and the question is still debated. Either way, the Hatata is now widely read as a landmark of reasoned inquiry.

The rival apps

Illustration: The rival apps

Two coworkers each swear their note-taking app is the best and the other’s is a mess. Both quote reviews from their own app’s fans.

A third asks them to agree on a test: how fast can each of them find last month’s notes? They run it. The result settles more than the shouting did, because it appeals to something both can check.

Try this today Pick one belief you hold because it is yours, and ask how you would judge it if someone else held it.
