The Benzene Ring evolving from imagination to proof
In 1865, German chemist August Kekulé was trying to understand the structure of benzene. Its chemical formula was known, but it was not clear how its carbon atoms were connected to one another.
At that time, straight-chain or branched structures were the more natural way to think about molecules. But for benzene, the idea of a ring of six carbon atoms was a completely new possibility.
Kekulé later described a dream in which he saw just such a circular arrangement of atoms. This experience is often linked to the origin of the idea of benzene’s ring structure.
But seeing a possibility and proving it are two different things.
Almost six decades later, in 1929, Kathleen Lonsdale studied the crystal structure of hexamethylbenzene using X‑ray crystallography.
Her work played a crucial role in providing decisive evidence in support of benzene’s hexagonal, planar structure.
So imagination revealed a possibility, but the scientific process subjected that possibility to the test of evidence.
The question here is not only about the scientific outlook.
Within us, our assumptions do not remain just assumptions. They gradually form a picture of who we are and how we see the world.
“This is just how I am.”
“This is just how the world is.”
“There is no way this could be otherwise.”
Slowly, this picture becomes part of our identity. When a new possibility appears, we do not look at it simply to see whether it is true or false. Somewhere inside, we also look to see whether it protects the picture we have built or threatens it.
This is where the structure of the ego becomes visible.
A belief is formed.
From that belief, an inner picture of ourselves takes shape.
Identity becomes tied to that picture.
Then arises the need to preserve it.
Whatever fits that picture feels easy to accept. Whatever challenges it begins to make us uncomfortable.
The scientific outlook works differently. It does not accept a new possibility just because it is appealing, and it does not reject it simply because it does not fit the existing picture. It brings every possibility before evidence.
Do I do the same with my assumptions?
Do I reject something because evidence is against it, or because it disturbs the picture I have built of myself and the world?
Do I accept something only because it agrees with my pre‑existing beliefs?
Has defending my assumptions quietly become my way of avoiding real examination?
