Realism
Realism holds that reality exists independently of human perception and thought. G. E. Moore's 'A Defence of Common Sense' (1925) and 'Proof of an External World' (1939) argued that ordinary objects — hands, tables, trees — are known with more certainty than any philosophical argument against them. J. L. Austin's 'Sense and Sensibilia' (1962) dismantled the sense-data theories that threatened this common-sense conviction. Scientific realism extends the claim beyond the observable: Hilary Putnam's 'Reason, Truth and History' (1981) and Richard Boyd's work on inference to the best explanation argue that our best scientific theories describe real, mind-independent structures, including unobservable entities like electrons and quarks, because the predictive success of science would otherwise be miraculous.
Worldview
An adherent of Realism moves through the world with a bedrock conviction that what they see, touch, and measure is genuinely there — not a projection of mind, not a social construction, not a dream. The table exists whether anyone looks at it. The electron exists whether anyone understands the equations. This creates a characteristic stance of epistemic confidence: the realist trusts that careful observation and rigorous science progressively reveal how things actually are, and that disagreements about reality can, in principle, be settled by evidence. Daily experience feels solid, straightforward, and shared — the world is a common ground, not a private theater.
Moral Implications
Because reality is objective and knowable, moral reasoning for the realist tends toward moral realism as well — the conviction that there are moral facts, not merely moral opinions, and that ethical inquiry can make genuine progress. Cruelty is wrong not because a culture says so but because it violates something real about human well-being. This grounds a robust sense of duty: if facts about suffering and flourishing are objective, then moral obligations are binding regardless of personal preference. The realist ethic favors accountability, evidence-based policy, and the idea that ignorance of consequences does not excuse harmful action.
Practical Implications
Realism underwrites the entire enterprise of modern science and engineering: if the world is mind-independent and lawful, then technologies built on accurate theories will reliably work. Medical treatments, bridges, and climate models are trustworthy to the degree that they track objective reality. Environmentally, the realist takes ecological data seriously — species loss, carbon concentrations, and ocean acidification are real problems demanding real solutions, not matters of perspective. In daily life, the realist orientation favors empiricism over ideology, institutional transparency, and a deep respect for evidence as the arbiter of public disagreement.
I. Time
Time is substantival and infinite — an objective, mind-independent dimension that flows in a single, deterministic direction. The realist treats time as a real container in which events occur; it would persist even if no events took place. Its structure is continuous and linear, reflecting the classical Newtonian picture that reality has a fixed temporal backdrop independent of observation.
Attributes
II. Space
Space is substantival and infinite — an objective, mind-independent container in which objects exist and events occur. It is flat and three-dimensional, operating locally: objects interact with their immediate spatial neighbors. Space exists independently of the matter it contains, consistent with classical physics and common-sense realism.
Attributes
III. Matter
Matter is substantival, finite, and locally situated — real, mind-independent stuff governed by natural laws. It is conserved: matter cannot be created or destroyed, only transformed. The realist takes matter as the paradigm of what is real, the fundamental furniture of the world against which all metaphysical claims must be tested.
Attributes
IV. Observer
The observer is a physical being rooted in a single moment and place, perceiving a world that exists entirely independent of that perception. Consciousness is present but incidental — a natural feature of a material organism, not a constitutive force in reality. The observer does not shape or alter what it perceives; it simply registers what is already there. Knowledge begins with direct sensory contact but accumulates over time through memory, records, and scientific inquiry, building an ever-more-complete picture of an objective world. Because reality is shared and mind-independent, multiple observers can verify one another's findings and converge on common truths.
Attributes
V. Energy
Finite and pre-existing, governed by natural laws. Conservation: Conserved — energy obeys the laws of thermodynamics within the objective, mind-independent world. Usage: Multiple — matter and energy can be reused and repurposed.
Attributes
VI. Information
Information is an objective feature of a mind-independent reality. Facts about the world are real informational states that persist whether or not anyone accesses them. The realist treats information as conserved in the physical sense: the laws of nature preserve a complete record of the universe's state. Information is continuous because the realist assumes reality has infinite precision.
