Nagaland governor PB Acharya on Monday said the current education system in the country was based on what the British had outlined and was promoting a kind of knowledge that made people self-centred, besides leading to obliteration of indigenous languages. Speaking as chief guest at the “Academic Assembly & Felicitation to Prominent Personalities, Governor Award and Scholarship to Students” programme organised by Janjati Shiksha Samiti (JSS), an NGO, at Kevijau village here on Monday, the governor said knowledge should make people realise their debts to society and the country. Pointing out that English was being favoured in the country, he stressed that content of a speech should really matter and not the language in which the speech was delivered. He also advocated for a primary education system that made learning of mother tongue mandatory.
