Occam’s Razor is a term used to refer to a philosophical idea or scientific principle whose task is to determine the most probable and simple explanation among many possible theories. The method or rule of Occam’s Razor states: The best and most likely explanation for an event is the simplest one. In other words, Occam’s Razor argues that the simplest theory is usually the best and most likely, assuming that nature uses the simplest tools to achieve a goal.
What is OCCAM’S RAZOR – meaning and definition in simple words.
In simple words, Occam’s Razor is a way to find the simplest and most logical explanation for what is happening.
As a classic example, we can cite the expression: “if you hear the clatter of hooves, then most likely it will be the most ordinary horses, not zebras.” The bottom line is that if you are not in Africa or a zoo where you can really find zebras, then most likely it is the most ordinary horses that make the sound of hooves.
It should be noted that the principle of Occam’s Razor does not guarantee to provide an absolutely correct solution or explanation of the situation. Its task, as already written above, is to find the simplest possible answer to the question of why a certain event occurred. That is why this principle cannot always be applied to solve all problems in certain areas, such as religion or science.
Why is the principle called a razor?
The answer to this question is very obvious and simple. The thing is that this principle is designed to cut off complex solutions like a razor. His task is to remove everything complex and unlikely and leave the most simple and logical.
Examples of Occam’s Razor.
- Event: There is a thunderstorm outside, and you see a bright flash through the window.
Explanation options:
A) There is a photo session near your window. The photographer takes a picture with a flash.
b) It’s just lightning.
The most likely and logical explanation is the answer “B”. - Event: Your home is near an airport, and you hear a lot of noise and vibration.
Explanation options:
A) Terrorists exploded a bomb near your house.
b) A plane flew by your house.
The most likely explanation is “B”. - Event: You have a dog and when you returned home, you saw that the apartment was a mess.
Explanation options:
A) The dog played and scattered things around the apartment.
b) There is an evil spirit in the house.
The most likely explanation is the answer “A”.
Origin of the term Occam’s Razor.
This concept is named after the monk William of Occam, who lived in the 14th century. In fact, Occam did not invent this principle, but he often used this technique to evaluate events. But not everyone agreed with Occam.
Some of his contemporaries often criticized this technique. They argued that cutting down to the simplest answer is not always the best and correct solution. Modern scientists also criticize this concept. The thing is that nature, very often, instead of simple systems, uses very complex and intricate mechanisms to achieve goals. An example is the pollination of flowers.
Using Occam’s Razor in practice in real life.
Many people use Occam’s Razor to eliminate competing theories. This is clearly seen in those cases where one of them implies the presence of an additional entity, and the other does not.
For example, there was a time when physicists assumed the existence of a certain “ether”. The ether was supposed to explain the existence of the universe. Blah’s problem is that the existence of this ether could not be proven. But when Einstein proposed his Theory of Relativity, the theory of the existence of the ether was rejected as unprovable and incorrect. The fact is that Einstein’s theory was much simpler and more logical. It did not contain various ghostly hypothetical substances. In this case, the principle of Occam’s Razor really turned out to be true and correct. But it is worth understanding that each situation is individual, and not always the simplest solution is the right one. Sometimes this principle really works, and sometimes it doesn’t.
