Splitting the (In)Difference: Why Fine-Tuning Supports Design

Given the laws of our universe, the initial conditions and cosmological constants had to be "fine-tuned" to result in life. Is this evidence for design?

The degree to which we should do so depends on our credences in controversial metaphysical issues.
