Now imagine what happened when people would offer a sacrifice but then it didn't rain or the sun didn't shine or their animals still got diseases or they were unable to have children--obviously, they concluded, they didn't offer enough. And so they offered more. And more and more. Because religion had built into it from the very beginning something called anxiety. You never knew where you stood with the gods. The gods are angry, the gods are demanding, and if you don't please them, they will punish you by bringing calamity. But what if things went well? What if it rained just the right amount and the sun shone just the right amount--what if it appeared that the gods were pleased with you? Well then, you'd need to offer them thanks. But how would you ever know if you'd properly showed them how grateful you were? How would you know you'd offered ENOUGH? If things went well, you never knew if you'd been grateful enough and offered enough, and if things didn't go well clearly you hadn't done . . . enough. Anxiety either way.
