Tamas (philosophy)

Tamas (philosophy) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tamas (philosophy) rather than just read about it. In short: Tamas (Sanskrit: तमस् tamas, lit. 'darkness') is one of the three guṇas (tendencies, qualities, attributes), a philosophical and psychological concept developed by the Samkhya school of Hindu philosophy. The other two qualities are rajas (passion and activity) and sattva (purity, goodness).

Key takeaways

Tamas (philosophy) belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Tamas (philosophy) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tamas (philosophy) from memory before moving on to harder problems.

Reference excerpt

Tamas (Sanskrit: तमस् tamas, lit. 'darkness') is one of the three guṇas (tendencies, qualities, attributes), a philosophical and psychological concept developed by the Samkhya school of Hindu philosophy. The other two qualities are rajas (passion and activity) and sattva (purity, goodness). Tamas is the quality of inertia, inactivity, dullness, or lethargy. Generally it is referred to as the lowest guṇa of the three.

Etymology The Vedic word támas refers to "darkness", and stems from the Indo-European word *temH-es, meaning "dark". Cognates with the Vedic include the Lithuanian word tamsà meaning "darkness", the Serbian word tama meaning "darkness", as well as the Latin word tenebrae meaning "darkness", the latter whence English tenebrous.

Hinduism In Samkhya philosophy, a guṇa is one of three "tendencies, qualities": sattva, rajas and tamas. This category of qualities have been widely adopted by various schools of Hinduism for categorizing behavior and natural phenomena. The three qualities are:

Sattva is the quality of balance, harmony, goodness, purity, universalizing, holistic, positive, peaceful, virtuous. Rajas is the quality of passion, activity, being driven, moving, dynamic. Tamas is the quality of dullness or inactivity, apathy, inertia or lethargy. Action that is virtuous, thought through, free from attachment, and without craving for results is considered Sattvic. Action that is driven purely by craving for pleasure, selfishness and much effort is Rajasic. Action that is undertaken because of delusion, disregarding consequences, without considering loss or injury to others or self, is called Tamasic. In Indian philosophy, these qualities are not considered as present in either-or fashion. Rather, everyone and everything has all three, only in different proportions and in different contexts. The living being or substance is viewed as the net result of the joint effect of these three qualities. According to the Samkya school, no one and nothing is either purely Sattvic, Rajasic or Tamasic. One's nature and behavior is a complex interplay of all guṇas in varying degrees. In some, the conduct is Rajasic with significant influence of Sattvic guṇa; in some it is Rajasic with significant influence of Tamasic guṇa, and so on. In Bhagavad Gita verse 18.32, the influence of tamas on buddhi is described as where a person "regards wickedness as virtue and virtue as wickedness".

Sikhism The Sikh scripture refers to tamas in its verses:

"The Fourteenth Day: one who enters into the fourth state, overcomes time, and the three qualities of rajas, tamas, and sattva." (SGGS [1]) "Those who embody the energies of sattva-white light, rajas-red passion, and tamas-black darkness, abide in the Fear of God, along with the many created forms." (SGGS [2]) "Your Power is diffused through the three gunas: rajas, tamas and sattva." (SGGS [3]) "Rajas, the quality of energy and activity; tamas, the quality of darkness and inertia; and sattva, the quality of purity and light, are all called the creations of Maya, Your illusion. That man who realizes the fourth state – he alone obtains the supreme state." (SGGS [4])

Worked examples

Example 1 — a first encounter with Tamas (philosophy)

Start with the simplest possible case. Write down what Tamas (philosophy) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tamas (philosophy) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tamas (philosophy) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tamas (philosophy)

In research: Tamas (philosophy) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tamas (philosophy) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tamas (philosophy) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Guṇa, so understanding it makes those chapters shorter.
In everyday life: Look for Tamas (philosophy) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
