Bedtime Story 


Understanding Natural Languages (and its weaknesses)


Linguistically, a natural language can be said to be comprising broadly of two primary components: linguistic objects and semantic terms.

Linguistic objects include stuff like sentences and terms that are one of the components of the language.

Furthermore, even the names of the linguistic objects such as sentences and terms are included in the language without the requirement of enclosing them either inside quotation mark or parenthesis.

Same is the case with semantic terms such as “truth”, “name”, “designation” etc, that even though they refer to the relationship between linguistic objects, they form part of the language without any kind of formal treatment.

Though it all seems harmless and benign, but what it does is that it gives us ordinary apes an extraordinary power that is highly vulnerable to misuse.

For every sentence that can be constructed in a natural language, it allows us to form another sentence in the same language that can declare the first sentence to be true or false.

In short, a natural language allows us to generate self-referential sentence.

Hence a sentence S can assert itself to be either true or false.

In some cases where S can claim its own falsity, then as we have seen in the case of Liar Paradox, it can clearly be reasoned out that S is both true and false.

So how do we get out of the trap that is laid out bare for us in all the natural universal languages?

Or how do we avoid them or go around them?

One way, Tarski says is to avoid the use of universal languages as much as possible since in many places we can do without them.

I know you are not going to accept this so easily so let me elaborate on this.

One place where the natural languages can surely be done away with is the sciences.

Take for instance chemistry.

The primary topics of discussion in chemistry are elements, molecules, chemical reactions and so on but not linguistic objects such as sentences or phrases.

In such a case the language can be restricted possessing limited vocabulary.

It will largely contain names of chemical objects such as “elements”, “thermal”, “equations”, “equilibrium”, “entropy” and so on.

This language will be largely deprived of the names of linguistic objects thus depriving it of being semantically universal.

Other branches of sciences can be given the same analogous treatment.

Another great educator and a teacher that I am aware of is Professor Subhashish Chattopadhyay in Bangalore, India.

While I narrate stories, Professor Subhashish an electronic engineer and a former professor at BARC, does and teaches real mathematics and physics.

He started the participation of Indian students at the International Physics Olympiad.

Do visit him here:


All his books can be downloaded for free through this link:


For edutainment and English education of your children, I recommend this large collection of Halloween Songs for Kids:
