As a child, I was fascinated by any branch of physical or biological science. Even today, I find great excitement in discovering the complexity and variability of the world we live in, getting a glimpse into the deeper reality that we mostly ignore in our everyday human activities.

That the variability of an organism to a certain extent is a constant and certain condition of life we admit, otherwise there would be no distinguishable individuals of a species.

Variability is the law of life, and as no two faces are the same, so no two bodies are alike, and no two individuals react alike and behave alike under the abnormal conditions which we know as disease.

It is time to recognize the variability of females, just as we do males.

In particular, Australia, because of its ancient geography, soil profile and distinctive weather patterns, is more adversely affected by climate variability than some other continents.

Sudden resolutions, like the sudden rise of mercury in a barometer, indicate little else than the variability of the weather.

The great fact of individual difference and variability (that is, inequality) is evident from the long record of human experience: hence, the general recognition of the antihuman nature of a world of coerced uniformity.
