Who wouldn’t argue that some things are objectively beautiful? Much of what we can see in the natural world would surely qualify: sunsets, snow-capped mountains, waterfalls, wildflowers. Images of these scenes, which please and soothe our senses, are among the most reproduced in all of civilization.

It’s true, of course, that we’re not the only creatures attracted to flowers. Bees and butterflies can’t resist them either — but that’s because they need flowers to survive.

Lying at the opposite end of the beauty spectrum are reptiles. They’ve had it pretty bad. Across decades of science fiction, their countenance has served as the model for a long line of ugly monsters, from Godzilla to the Creature in the “Creature From the Black Lagoon” to the Gorn in “Star Trek.”

There may be a good reason for our instinctive attraction to some things and distaste for others. If our mammalian ancestors, running underfoot, hadn’t feared reptilian dinosaurs they would have been swiftly eaten. Similarly, nearly everyone would agree that the harmless butterfly is more beautiful than the stinger-equipped bee — with the possible exception of beekeepers.

Risk of bodily harm appears to matter greatly in our collective assessment of what is or is not beautiful. Beauty could very well be a way for our senses to reassure us when we feel safe in a dangerous universe.

If so, I can’t help but wonder how much beauty lies just out of reach, hidden in plain sight, simply because we have no more than five senses with which to experience the world.
