The Lamp of Knowledge on Ignorance: Twenty-Five

This conception of "asat" plays a crucial role in various Indian philosophical systems, particularly Advaita Vedanta, Nyaya, and Vaisheshika, where detailed discussions on the nature of reality and different levels of existence have been undertaken. In these philosophies, "asat" represents a category that is utterly non-existent, distinguished from "mithya" (that which once existed or appears but later dissolves) or "anirvachaniya" (that which is neither real nor unreal).

Tabula Rasa is a Latin phrase literally meaning "erased tablet" or "blank slate." In philosophical terms, it signifies that the human mind possesses no inherent, inborn knowledge. At birth, the human mind remains like a completely blank slate. Life's experiences, environment, education, and sensory knowledge gradually write upon that empty page.

This concept is primarily associated with the English philosopher John Locke (17th century). He argued that the human mind develops through experience and sense perception alone—that is, there are no innate ideas. A child's mind at birth is like blank paper. Gradually, society, education, experience—all these accumulate knowledge upon it. In Locke's "tabula rasa" conception, the human mind at birth remains completely empty, as if nothing is written on white paper. Experience, sensory perception, and education gradually fill that blank page; but this notion finds no correspondence whatsoever in Indian philosophy.

Naiyayikas believe that knowledge comes through experience, yet the soul brings sanskaras from previous births. Therefore, it is not entirely empty. In Advaita Vedanta, the soul is said to be inherently knowledge-full—but that knowledge remains unmanifest at birth due to the covering of avidya. Here, the mind is not empty; rather, latent knowledge lies concealed. Yoga philosophy states that a child's chitta contains many sanskaras from previous births; thus new experiences merge with those old impressions. However, in Buddhist philosophy, there is no concept of a permanent soul; they regard the mind as a momentary stream. Therefore, there is no inherent knowledge at birth—in this aspect, Buddhist thought approximates Locke's "tabula rasa."

Thus, Western 'tabula rasa' finds its closest parallel with Indian Buddhist philosophy, has partial correspondence with Nyaya philosophy, but is directly rejected by Advaita Vedanta, since according to them, knowledge always remains in latent form, merely covered by avidya. To illustrate with analogies—

Locke's 'tabula rasa' is exactly like completely blank paper. At birth, that paper is utterly empty; later, experience and education's pen gradually accumulates writing. But Advaita Vedanta would say the mind is not blank paper, but rather a luminous mirror—one that can radiate light from birth itself. However, dust has settled upon the mirror (avidya or maya). Experience and knowledge constitute the process of wiping away that dust, allowing the mirror's true brilliance to emerge. Nyaya philosophy would say the paper is not entirely blank—faint impressions or water stains from previous births remain upon it (sanskaras). New writings settle upon those old marks. Buddhist philosophy would say 'mind' is neither paper nor mirror. Rather, mind resembles lines drawn in sand each moment, where waves come and leave new impressions, then immediately erase them. It contains no permanent writing or light. Thus, through analogy: According to Locke, mind = blank paper; According to Vedanta, mind = dust-covered mirror; According to Nyaya, mind = paper with old stains; According to Buddhism, mind = wave-impressions on sand.

"The world will already be known"—this intriguing notion points to a profound condition where our perception and experience of the world does not emerge from a 'tabula rasa' or blank slate. Instead, the world in its totality—as objects, events, and experiences—is considered to be inherently a given, a pre-existing cognitive framework, or a set of deeply embedded assumptions that influence and precede our conscious perception.

This 'prior knowledge' is a rich tapestry woven from preconceptions, cultural inclinations, inherited beliefs, fundamental metaphysical assumptions, linguistic structures, and even deeply embedded biological tendencies regarding how reality functions. This complex collection significantly influences, shapes, and subtly filters how subsequent observations, inferences, and interpretations about the world are processed and understood. It powerfully highlights our inherent subjectivity as cognitive beings and the inevitable 'filters' through which we perceive and construct objective reality. Our engagement with the world is always already informed, never truly beginning from a neutral, unconditioned point. This concept connects discussions of cognitive bias, cultural relativism, and the architecture of human perception.

Going deeper, this 'prior knowledge' can be understood through various lenses. From a philosophical perspective, it echoes Kant's transcendental idealism, where the mind does not merely receive sensory data but actively structures it according to innate categories of understanding. We do not simply perceive space and time; we perceive in space and time—these being fundamental structures of our cognition. Similarly, our cultural upbringing instills a particular method of categorizing events and attributing value to them. A forest might be seen by one culture as a resource source, by another as a sacred grove, or by a third as merely a collection of trees. These different interpretations are not based solely on objective observation but are heavily influenced by pre-existing 'cultural schemas.'

Cultural Schema is a concept used in psychology and anthropology. Simply put, a schema is a structured framework or mental blueprint within the mind—that organizes our thoughts, behavior, and experiences. When this develops under cultural influence, it is called a cultural schema.

Every culture has its own values, beliefs, behaviors, language, symbols, stories, and customs. From childhood, people internalize these elements through family, society, education, and practice. This creates a mental framework in their minds—which helps them make decisions, understand others, and interpret new experiences.

Let me provide some examples.
Hospitality: In Bangladeshi or Indian culture, when guests arrive, they are served considering "atithi devo bhava" (guest is god). This attitude is a cultural schema—which might differ in Western cultures.
Marriage: In the West, marriage often means a personal decision between lovers; while in South Asia, there is significant familial and social participation. These different perspectives are the work of cultural schemas.
Respect: In many Asian societies, showing special reverence to elders is considered mandatory. This is that culture's mental framework.

'Cultural Schema' is a kind of "invisible mental blueprint" created in the minds of people raised within a culture. It influences our behavior, interpretations, communication, and decisions. Explaining cultural schema in light of Indian philosophy—

1. Dharma: In Indian culture, "dharma" is not merely religious ritual but a framework of morality, duty, and social roles. For instance, a son's duty is to serve his parents—this is a cultural schema. This is taught from childhood, so how a person behaves in any situation is determined by this mental framework.

2. Sanskara: Sanskara means influences or impressions accumulated in the human mind from birth. Marriage ceremonies, first rice feeding, sacred thread ceremonies, etc., are not merely rituals; they form cultural mental frameworks in the individual's mind. For example, in first rice feeding, giving rice to a child means—"from now on, they are part of social food consumption." Thus social responsibility and identity become established in the child's mind.

3. Social Vision: In Indian society, guru-disciple relationships, respect for elders, or the concept "atithi devo bhava"—all these are parts of cultural schema. For instance, when a guest comes home, the child learns that they must respectfully offer water. This is a kind of unconscious cultural framework that passes from generation to generation.

4. From Advaita Vedanta Perspective: Advaita Vedanta would say—these cultural schemas are actually "mental sanskaras" created at the level of avidya, which mold the jiva according to social patterns. But these are not the soul's true nature; they are merely mental impressions (vāsanā) that must be transcended on the path to liberation.

Cultural schema in Indian philosophical language is a mental framework formed by 'sanskara + dharma + social vision,' which drives our thoughts, decisions, behavior, and relationships. Western psychology calls this schema, while in Indian terminology it can be understood as "sanskara" or "unconscious mental impressions." "Schema" and "scheme"—though these two words seem close, they actually carry different meanings.

Schema—derived from Greek skhēma, meaning "shape, form." Used in modern psychology, cognitive science, linguistics. Here schema means mental framework, structure, organized blueprint of knowledge within the mind. Examples: cultural schema, cognitive schema, self-schema, etc. On the other hand, Scheme means plan, framework, program, strategy. Generally used to indicate planning or steps for implementing work in real life. Examples: five-year scheme, government housing scheme, etc. Simply put, Schema—knowledge structure within the mind; Scheme—some plan or project in the external world.

The Sapir-Whorf Hypothesis or linguistic relativity is an extremely important concept in linguistics and anthropology. It is called the Linguistic Relativity Theory. Its main proposition—the language in which people speak influences their thinking, perspective, and way of perceiving reality. That is, language is not merely a medium of communication but also shapes how humans understand the world.

American linguist and anthropologist Edward Sapir conducted deep research on Native American languages and demonstrated that language is not merely a communication medium but reflects a society's culture, lifestyle, and thought patterns. According to him, understanding language structure provides insight into that society's mentality and culture. His student and follower, American linguist, thinker, and amateur firefighter Benjamin Lee Whorf analyzed how language structure influences human thinking. He researched the Hopi Native American language and showed that their concept of time (past-present-future) differs from European languages. Consequently, their time-consciousness is also different. Through this, he sought to prove that language influences the way reality is understood. Their joint thinking gave rise to this hypothesis.
