Predictability is not how things will go, but how they can go.

Ideas can't die, not because they are conceived by humans, but because time begets them.

Religion and philosophy have different logics, speak different languages. Their logics are mutually exclusive, languages sometimes overlapping. It is hard to find something really common in them.

The most crucial problem with intellectual learning is that it receives the unknown on the grounds of the known.

Fortunately or unfortunately, the greatest authority on matters of life is life itself.
