"Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution."

"The existence of isomers, differing only in the spatial arrangement of their constituent atoms, provides strong evidence for the three-dimensional nature of molecules."
— from Habilitationsschrift, University of Zurich, 1893
"The primary valencies are those which are satisfied by the formation of ions, while the secondary valencies are satisfied by the formation of non-ionizable groups."
— from Neuere Anschauungen auf dem Gebiete der anorganischen Chemie, 1907
All quotes by Alfred Werner (414)
The idea of a fixed valency for each element is a simplification that hinders progress in understanding chemical bonding.
The concept of coordination number is a more fundamental property than valency in many cases.
The spatial arrangement of atoms is not merely a theoretical construct, but a tangible reality with observable consequences.
The success of my theory in explaining and predicting phenomena that were previously inexplicable is its strongest argument.
The traditional methods of representing chemical structures are often inadequate for coordination compounds.
The idea of a 'central atom' surrounded by 'ligands' provides a powerful model for understanding complex inorganic structures.
The existence of geometric isomers in coordination compounds is a clear indication of their non-planar structures.
My work has opened up an entirely new field of inorganic chemistry, rich in possibilities for further research.
The concept of 'coordination' is not limited to inorganic compounds, but has broader implications for chemical bonding in general.
The ability to isolate and characterize the predicted isomers was crucial for the acceptance of my theory.
The prevailing theories of valency were insufficient to explain the observed properties of many inorganic compounds.
The idea that atoms can form bonds in directions other than those dictated by simple valency rules was a radical departure.
The chemical community was initially skeptical of my ideas, but the experimental evidence eventually proved their validity.
The study of coordination compounds provides a unique window into the fundamental nature of chemical forces.
The distinction between ionic and covalent bonding is often blurred in coordination compounds.
My theory provides a rational basis for understanding the colors and magnetic properties of many transition metal complexes.
The challenge was to move beyond two-dimensional representations and embrace the three-dimensional reality of molecules.
The concept of 'ligand field' was a later development, but its roots lie in my understanding of the spatial arrangement of atoms.
The resistance to new ideas in science is often strong, but persistence and experimental proof ultimately prevail.
The study of coordination compounds bridges the gap between inorganic and organic chemistry.
