The larger the island of knowledge grows, the longer the shoreline — where knowledge meets ignorance — extends. The more we know, the more we can ask.Of course not all ignorance is created equal. Not knowing the motions of the planets, or the root causes of our diseases, is fundamentally different than not knowing where life exists outside of our solar system, or the specific proteins involved in ALS.
Science is progressive in that future knowledge builds on erasing the ignorance of the past. The problems and breakthroughs we've made so far empower us to push ever onward in our pursuit of knowledge. We know we can do it again because we've done it before.
The progress science makes sometimes takes a circuitous route to improving our quality of life. The discovery of TDP-43 in ALS, for example, will not cure ALS overnight. As MLK once remarked, the moral arc of the universe is long, but it bends towards justice. Maybe the ignorance-erasing arc of science is long, but it bends constantly towards improving our lives.
