Imagine a child born in Accra. She learns to speak at home in Twi—the language of her mother, her grandmother, her ancestors. She dreams in Twi. She argues with her siblings in Twi. She thinks her deepest thoughts in Twi.

Then she goes to school. And everything changes.

Mathematics is taught in English. Science is taught in English. History is taught in English. The language of serious thought, of examination, of professional success—is English. Twi becomes a home language, a social language, a language of tradition. English becomes the language of intelligence.

This is not education. This is architecture. And it is the most successful and least examined instrument of mental colonization on the continent.

The TSA Question

What is lost when a people learn to think in someone else’s language?

This is not a question about communication. It is a question about cognition. The language in which you learn to reason determines what concepts are available to you, what distinctions you can make, what ideas feel natural and what feels foreign. When an entire continent is educated in languages imported from across an ocean, something fundamental is displaced—not just vocabulary, but the very structure of thought.

The Installation

How Colonial Education Made European Languages the Languages of Intelligence

The British did not arrive in West Africa and announce: “We will now teach your children in English because it is superior.” That would have been too crude. Instead, they did something more effective: they installed English as the language of power while systematically discrediting African languages as unfit for serious thought.

The mechanism was simple. First, they called African languages “dialects”—a word that carried the implication of incompleteness, of being a lesser version of a “real” language. A language has grammar, literature, philosophy. A dialect is just… talk. The English had a language. The Fante had a dialect. The difference was not linguistic—it was political.

Second, they built a school system in which every subject of value was taught in English. Mathematics, science, history, geography, literature—all in English. African languages were permitted only as a bridge, a temporary scaffold to be removed as soon as possible. The message was unmistakable: serious thinking happens in English. Your mother’s tongue is for the market, for the home, for what is personal and unimportant.

Third, they created an economy in which English proficiency was the gatekeeper to opportunity. The clerk’s job, the teacher’s post, the administrator’s office—all required English. The message again: if you want to matter, you must leave your language behind.

By the time colonialism formally ended, the installation was complete. Africans themselves believed that English was the language of intelligence. Africans themselves enforced English-only policies in schools. Africans themselves looked down on students who spoke their mother tongues in the classroom.

The colonizer did not need to stay. The colonized had internalized the hierarchy.

The Split Consciousness

The Child Who Thinks in Twi at Home and English at School

There is a Ghanaian child. Let us call her Ama.

At home, Ama speaks Twi. She tells her grandmother about her day. She jokes with her siblings. She negotiates with her mother about chores. In Twi, Ama is fluent, expressive, confident. She thinks in Twi without effort—the language is not a tool she uses but a medium she inhabits.

At school, Ama is required to speak English. When she raises her hand, she must formulate her thought in a language where she does not dream. She must translate before she can speak. The thought that was alive in Twi becomes stiff in English. The nuance is lost. The confidence falters.

What does this do to Ama’s mind?

Over time, Ama learns something that no teacher ever explicitly teaches: her real thinking—the thinking that is deep, natural, effortless—is not acceptable in the classroom. The classroom requires a different kind of thinking: slower, more careful, more constrained. The classroom teaches her that her natural intelligence is somehow inadequate. That to be intelligent, she must think in a foreign language.

This creates a split consciousness. Ama develops two ways of being: the person she is at home—fluent, confident, fully herself—and the person she is at school—hesitant, self-conscious, performing for approval. Over time, the school self becomes the “real” self, the self that matters. The home self becomes private, personal, less important.

This is not an accident. This is the mechanism through which language colonizes the mind.

The Kenyan writer Ngugi wa Thiong’o describes it as the “colonial alienation” of the African child:

“The colonial child was made to see the world and where he stands in it as seen and defined by the colonial culture. He was made to see his past as one wasteland of non-achievement and his present as a dark reality from which he had to escape to the light of European culture.”

The escape route was language. The destination was a mind that could think, but only in borrowed categories.

The Untranslatable

Sankofa, Ubuntu, Ma’at—Concepts That Cannot Be Carried Into English

When a language dies, something dies with it. Not just words—ways of seeing, ways of knowing, ways of being in the world.

Consider what is untranslatable.

The Akan concept of Sankofa—the bird that flies forward while looking back—cannot be captured in English. “Return and retrieve” loses the visual philosophy, the embedded instruction about the relationship between past and future. To translate it as “learning from the past” is to flatten it, to lose the specific relationship between past and present that the word encodes.

The Yoruba concept of Ori—the inner spiritual head that determines destiny—has no English equivalent. When Yoruba philosophy is taught in English, this concept is reduced to “destiny” or “fate,” losing the nuanced understanding of how the individual relates to the cosmic order.

The Kiswahili concept of Utu—humanity, personhood, the quality of being human in relation to others—is the foundation of an entire ethical system. Ubuntu in Nguni languages carries similar weight. These are not just words. They are philosophical frameworks. When we reduce them to “humanity” or “kindness,” we lose the communal epistemology they carry—the understanding that a person is a person through other persons.

The Kemetic concept of Ma’at—truth, justice, balance, cosmic order simultaneously—requires four English words and still misses the unity. Ancient Egypt developed one of the most sophisticated ethical systems in human history, and its central concept cannot be translated into the language that now dominates African education.

When we teach African children in English, we do not just teach them a new language. We teach them to think in categories that cannot accommodate these concepts. We teach them that their ancestors’ deepest insights are untranslatable—which means, implicitly, that they are unimportant.

The concepts that cannot be translated are not gaps in African languages. They are gaps in English. The loss is not what English fails to carry—it is what we no longer know we had.

The Hierarchy

Why English Is “Professional” and African Languages Are “Traditional”

Walk into any African office, any boardroom, any government ministry. Observe the language spoken. English (or French or Portuguese) is the language of professional life. It is the language of memos, meetings, contracts, and official communication.

African languages are for the market, for the home, for ceremonies and celebrations. They are “traditional.” They are not “professional.”

This distinction is not neutral. It is a hierarchy. And it operates invisibly, enforced daily by every African professional who chooses English over their mother tongue in a professional context, by every institution that requires “formal” language, by every young person who learns that to be taken seriously, they must speak like someone else.

Consider the job interview. A candidate who speaks fluent English is perceived as competent, intelligent, professional. A candidate who speaks only their mother tongue is perceived as uneducated, regardless of their actual knowledge or capability. The language becomes a proxy for intelligence.

Consider the academic conference. The scholar who presents in English is taken seriously. The scholar who presents in Wolof or Hausa is seen as speaking to a local audience—not to the “international community.” The hierarchy is invisible, but it determines who gets heard, who gets published, who gets funded.

This hierarchy is not natural. It was constructed. And it can be dismantled—but first, it must be seen.

The Alternative

Bilingual Education That Centers African Languages as Languages of Thought

The argument against African-language instruction is always the same: “English is the global language. Our children need English to compete.”

This argument assumes what it should prove. It assumes that the choice is either English-only or no English at all. It assumes that teaching in African languages means abandoning English. This is false.

The alternative is not English or African languages. The alternative is both—but differently.

Imagine a classroom where:

• A child learns to read and write first in their home language, building literacy skills that transfer naturally to English later
• Mathematics and science are taught in the language where thinking is deepest, with English introduced as a second language, not a replacement
• History and social studies begin with local knowledge, local heroes, local achievements—taught in the local language—before expanding to continental and global contexts
• English is taught as a foreign language, with the same respect and methodology used to teach French in English schools
• African literature is taught in African languages, with translations available for those who need them
• Philosophical concepts are explored in the languages that birthed them, then discussed in English as a second language

This is not fantasy. This is how education works in every other part of the world. In Finland, children learn in Finnish. In Japan, children learn in Japanese. In China, children learn in Mandarin. Only in Africa do we insist that children must learn in a foreign language to be educated.

The objection: “But we have many languages! Which one would we choose?”

This is a logistical challenge, not an insurmountable obstacle. Tanzania chose Kiswahili. Ethiopia chose Amharic. Nigeria could choose Hausa, Yoruba, and Igbo as regional languages of instruction, with English as the common language. Ghana could choose Twi, Fante, Ga, Ewe, and Dagbani as languages of instruction in the early years, with English introduced gradually.

The question is not whether it is possible. The question is whether we have the political will to do it.

Closing: The Question

The question is not whether your students can speak English.

They can. They will. English is not going away. It is a useful tool, a global language, a means of communication with the wider world. No one is arguing that African children should not learn English.

The question is deeper.

The question is: can your students think in the language where their thinking is deepest?

The question is: do your students know that their home language is a language of intelligence, of philosophy, of knowledge?

The question is: have your students been taught that their grandmother’s tongue is sufficient for serious thought—or have they been taught that it is a dialect, a relic, a language of tradition but not of progress?

The question is: when a child asks a question in Twi, do you tell them to speak English—or do you welcome the question and answer it in the language where the child is most alive?

You cannot think freely in a language that was forced on you. The question is whether we will reclaim the languages where our thinking is deepest—or continue to think in borrowed tongues.

The question is not about policy. It is not about curriculum. It is not about the Ministry of Education. It is about you. In your classroom. Tomorrow morning.

The installation of English as the language of intelligence took centuries. It will not be undone overnight. But it can be undone—one classroom, one teacher, one child at a time.

The question is whether you have the courage to begin.
