Carr’s 1961 quote reminds us that facts do not become history by themselves. History emerges when evidence is selected, organized, interpreted, and placed into a meaningful story.
When you encounter fiction, test it. Every story you’ve encountered is a recomibination of existing elements within our universe. We are not a deities, we are explorers.
Speculation has a real place in science and in your worldview, but speculative ideas are not established truths. They are starting points, possibilities, or failed guesses that must eventually be supported, revised, or discarded.
