More has been discovered, invented, and achieved
In modern times than in all the past put together.
But just as there is no leaf or fruit without a root,
There is no present without a historical past.
It is true that we live in an age of science,
And we in an age of multiculturalism.
So we need to know about science,
But also something about other cultures
That contributed to science in centuries past.
Ancient science grew in many lands
And in different cultures from the efforts
Of men and women of ages long past,
Speaking different languages, and holding
Entirely different and even strange worldviews.
Their legacies and relics, writings and books
Have been unearthed and interpreted
By delving archaeologists and probing scholars.
What we have learned from their efforts
Is that all through human history,
All cultures have had their thinkers,
Creative artists and discoverers.
Inquisitive minds always explored
And reflected on natural phenomena.
These were the scientists of any place and time.
Their discoveries and worldviews
Formed the science of their time and place.
In this context we must recognize
Science as an human enterprise.
Wonderment about the natural world
And the urge to understand and explain
Are intrinsic to our nature and spirit.
They give rise to countless interpretations.
Let us recognize that we are all heirs
To ideas, insights and breakthroughs
Initiated by ancient peoples, all affiliated
To particular cultures and periods.
We must look upon whatever they did
As humanity’s collective heritage,
Rather than as belonging just to this group or that.
From this perspective, we must realize
That some aspects of ancient science
Need to be discarded and replaced
By better-informed findings of later times.
We respect other modes for their efforts,
But need, perhaps should not try to show
That those old sciences are still valid:
That geomancy, numerology, astrology, phlogiston
Have the same scientific validity today
As modern geology, astronomy and biochemistry.
Thousands of profusely foot-noted papers
And countless erudite volumes
Have been written on the subject matter
Of what is called pre-modern science.
In these notes let us review some names
And findings of former times.

“ That some aspects of ancient science
Need to be discarded and replaced.”
but not forgotten.
Good point.
