Danger of Curiosity – It Killed the Cat

Danger of Curiosity – It Killed the Cat

I am sure you have heard the old saying, “Curiosity killed the cat.” Perhaps someone used it to give you a warning about the danger of curiosity. In other words, they wanted you to stay just as you are and not ask questions.

However, asking questions is part of being human. The truth is that cats are not particularly curious. If you observe them, you may notice that they are extremely cautious. They may watch from a distance or test something cautiously with one paw. Humans, however, are not so cautious in their approach to things.

Humans are born into the world with a lot to learn, and they have to do it in a short time. Perceptual curiosity is the tool babies use to learn about the world. Adults who know the dangers of the world are always putting up barriers because the infant hasn’t learned the danger of curiosity.

However, perceptual curiosity is not restricted to humans. Animals such as dogs and crows (and even cats) display curiosity as they randomly explore unfamiliar objects. They may be thinking, “Does it move?” or “Can I eat it?” That is not much different from an infant’s investigation of the surroundings.

There is another level of curiosity only seen in humans. Psychologists call it epistemic curiosity. Jordan A. Litman of the psychology department at the University of South Florida wrote a paper on epistemic curiosity in the Encyclopedia of the Sciences of Learning. He defined epistemic curiosity as “the desire to obtain new knowledge (e.g., concepts, ideas, and facts) expected to stimulate intellectual interest…or eliminate conditions of informational deprivation.” Epistemic curiosity requires an understanding of complex language and the ability to think and reason. It goes beyond infant or animal curiosity. Humans display epistemic curiosity after their perceptual curiosity has given them the necessary tools.

Epistemic curiosity leads humans to go beyond creating simple tools, which some animals can do, to imagining and inventing new creative possibilities. It has paved the way for creativity in music, art, and science. Humans have an intellectual interest in things beyond what is required for mere survival. We want to eliminate “informational deprivation.” We wonder what would happen if…, and what will happen when…” We want to know if there is a God. We want to know if this life is all there is. This ministry seeks to encourage that curiosity and encourage people to follow the evidence where it leads.

The problem comes when people choose to stay at the perceptual curiosity level. “If our senses can’t detect it, then it doesn’t exist.” “The cosmos is all there is or was or ever will be.” “Curiosity killed the cat, so, therefore, don’t be curious.” “Don’t ask too many questions.”

If someone wants you to stay just as you are and avoid the danger of curiosity–beware! Don’t be afraid to ask the crucial questions. Sadly, it is not always unbelievers who avoid the danger of curiosity. God is not afraid of our questions. Let us, like Job, not be afraid to ask the questions–and accept the answers.

Cat Tongues and Papillae

Cat Tongues and PapillaeAlexis Noel and David Hu have been researching cat tongues as reported in the Proceedings of the National Academy of Sciences (December 2018). Using 3-D scanning with micro-computed tomography, they have discovered some interesting things.

The backward facing barbs (papillae) on cat tongues are not cones as had been previously thought. They are actually hollow structures similar to scoops for dipping ice cream. They have a U-shaped cavity that holds fluids extremely well. This shape enables cats to use the force of surface tension to pull up water as they lap it. It also allows them to wick saliva deep into their fur. When cats lick themselves, saliva is distributed all the way down to the roots of the hairs. Cats don’t have sweat glands except on their paws, so the distribution of saliva removes heat from their skin.

The papillae also allow cats to lick up oils and other contaminants on their fur. This not only keeps the cat clean, but it avoids odors. Applying this discovery may open the door to a whole new line of materials for use in home and industry. Dr. Noel gives one word of warning. Don’t let your cat lick a microfiber blanket, because the cat’s tongue will stick to the blanket!

Cat tongues are not like sandpaper but rather like Velcro. Velcro was discovered by scientists watching other examples in the natural world. Humans have copied the design of materials found in living organisms to create many of the substances we take for granted. We see God’s creative genius everywhere we look. “We can know there is a God through the things He has made” (Romans 1:19-20).

Seeing With Whiskers

Seeing with Whiskers
Have you ever wondered how cats can navigate in a dark room? Dr. Hendrick Van der Loos is an expert on the role of whiskers in animals. His research team at the University of Lausanne in Switzerland has shown an amazing demonstration of what cats can do by seeing with whiskers.

They blindfold cats and put them in a room with toys and other obstacles scattered around. The cats could navigate the room as well as cats with full sight because of their whiskers. The ancient Egyptians believed that cats had mysterious powers because they observed cats hunting mice in complete darkness.

We now know that not only cats but also walruses, pigs, seals, moles, and even whip-poor-wills have whiskers designed to meet their specific needs. The secret in all of these animals is that they possess specialized touch-sensitive hairs called vibrissae which are embedded deeply in the skin and resting in tiny sacs of fluid which pivot like a straw in a bottle of soda-pop. Brushing a whisker generates an electric signal in the fluid which is surrounded by nerves. The nerves feed the signal to the brain. This system is so sensitive that animals can detect the change of air currents around an object. They are seeing with whiskers which serve essentially as a tactile third eye.

A blindfolded cat can catch and kill a mouse. High-speed photography shows that a cat on the prowl for a mouse holds its whiskers in a fan-shaped pattern. Just before pouncing, the cat shifts its whiskers forward around its mouth. When the cat makes contact with the mouse, the whiskers tell the cat which way the mouse is dodging. As the whiskers wrap around the mouse, the cat can detect ahead of time which direction the mouse is trying to go.

A walrus will cruise around the floor of the ocean with its rump up and its head down stirring up the sea floor, so sight is useless. The walrus roots through the clouded water sorting out anything that might be good to eat by seeing with whiskers. Since walruses feed at night, there is the added benefit of being able to eat 24 hours a day. Moles have whiskers around their feet and tails which can detect insects in total darkness underground. Whip-poor-wills, nighthawks, and nightjars have whiskers near their beaks and are active after dark.

Human whiskers are just hair, and they serve only decorative purposes. True whiskers were designed by God to provide special tools for animals to survive. They allow the normal processes of life to be carried on 24/7, and they speak eloquently of God’s wisdom and design in the world all around us.
