Can you think without la language?
If you don’t have words how do you know what your thing about?
Pretty much No.
Studies of feral children, and for example the underclass of London show that lacking a good understanding of language makes thinking as we understand it very difficult.
Edgar Rice Burroughs notwithstanding, if you want to think clearly and be able to manipulate complex thoughts and ideas, you need to master at least one language, and preferably more than one, with additional support from music, mathematics, and even physical training such as in sports, or skill sets such as archery or fencing.
