What is an “opaque” object? The answer is simple – which is not transparent. An “opaque” statement is something which can’t be understood. Opacity points to the fact the “truth” is under cover. But how can “truth” itself be “opaque”?
To get an answer to that, Let’s see what actually “truth” is. “Truth” is the fact that is proven true. Now how can this be proven? On the basis of facts or beliefs. Truth can be of two types – universal and perceived. Universal truths are proven beyond controversy and can’t be wrong in any case – e.g. “The Earth revolves around the Sun”. Till date, this statement can’t be challenged.
In case of perceived truth, the basis is the common beliefs. The problem is – beliefs vary. Let’s consider a very common example. An atheist believes there is nothing called “God” and he believes this is the “truth” – based on the beliefs and perceptions he have. On the other hand, a believer believes in the existence of “God” and he has got his own set of logic as well. In this case no one is lying – both are true in their own ground. So what’s the “truth” here? This is where the common perspective of truth gets hit – the “truth” becomes opaque. This can even be correct for “scientific truths” as well, because many theories in science can’t be proven undoubtedly till date. If something new comes up, may be science will have to be written again and today’s “truth” will be proven wrong tomorrow. This has happened previously (think of Einstein’s paper on General and Specific Theory of Relativity) and can happen anytime – again.
Think in our own life. You made a decision yesterday, on the basis of some facts which you perceived to be “true”, and they were “true” at that time. Now, today when you look back, you feel your decision was wrong, because that “truth” is not true in today’s perspective. Now you think – was the yesterday’s decision based on a lie? The answer is – No, because that was “true” then, may be not now.
This is how the definition of “truth”, what we all read from childhood, changes when it’s applied in real life scenarios. There is always a grey area between the transition of black and white. “Truth” sometimes resembles the “grey” zone – an unknown opaque reality.
