First one ought to have a command of one’s own language.

A person should learn his own language completely.

The language experts and psychologists say:

- "A person can solely think in his/her own language, can dream in his/her  own language and can be happy in his/her own language.”

Well, there must  still be some envious monolingual psychologists and linguists around...

Francis Bacon regarded linguistics as a respectable way of wasting time. Did you know that there is not a single definition of language upon which all authorities agree.

Since language probably includes everything ever conceived or uttered by humans, it is virtually impossible to accurately characterize it. All  thoughts, intentions, desires and  feelings are conveyed by it. It is impossible for one to master all of the aforementioned in a lifetime.  Therefore, there is no such thing like being able to learn one´s language completely.

Language both sets the limits of human thought and serves a means for its expansion. Even the most prominent poets, writers or linguists  can only claim to have reached the bleeding edge of it.  Because thanks to their collective efforts, the scope of language is continually  expanding.

My teacher says :

- " You   cannot   think   in   a   foreign   language...You   can   solely   think   in   your   native   language... You   can   think,   but  in   your    own   language    only... You   cannot   think,   love   and   dream   in   a   foreign   language,  

but   in   your   own   language   only..."

"If you say to somebody, for example,  "I love you",  this is not a sincere, fair and honest, but  affected expression/emotion"

do you take what others say for granted?

 change the teacher and start thinking for yourself,it is the sign of maturity

scientific facts  only...it is a scientific fact...

Sorry, Yilgun, but I disagree. It is possible to dream or think in a foreign language. And I don´t quite get what your teacher meant by "being able to love in one´s native language only"

There are many things allegedly impossible to be done in y/our second language. For example, they say you´d use your native language for calculations. The correct word here must be "prefer".  Similarly, you could dream in another language. The amount of the foreign language conversation you get involved in during a dream on the other hand will be more or less the same as your daily use of that language.

Regarding your inner thoughts, you could technically use your second or third language here without any problems. Your native language will be silently filling in any missing words or syntactic rules with the help of your imagination.

Love can be felt for anyone regardless of what language he/she speaks. We often see people try to learn their lovers´ native language. The need for communicating with tyour sweetheart provides you with one of the strongest motives to learn a language. If your lover is Dutch, you would learn to say Ik hou van jou or if she is Finnish that would be Mina rakkastan sinua and believe me you will soon be able say it with befitting intonation, enthusiasm and your lover will love your pronunciation.  Love rarely happens in lifetime and when it happens it knows no boundaries, neither lingual nor cultural.

Thank you.

But some language experts and psychologists say it is impossible…

They say  :

- “People cannot  think and dream in a foreign language, but their own language only.”

- “People cannot like / love in a foreign language.”

This is their opinion. A thesis.

It is a psychological  complicated matter…

They said so in a symposium in Ankara…

I cannot find a scientific research or study on this topic.

And thus not necessarily a fact

It is difficult to provide measurable and incontestable means for testing language acquisition, or to establish how close you are to learning your native language completely as language is a living organism undergoing constant change.

Joseph Conrad-Heart of Darkness-author was a Pole who wrote in English.He is recognised writer ,compared to Rudyard Kipling,achiving mastership with using symbolism and lush metaphors.

He loved,wrote and thought in a foreign language..paradox????
