“Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.”
— Marie Curie

We often fail to appreciate how inextricably linked the present is to the past, and that leads to a neglect of valuable historic information, which in turn allows the reappearance of evils that have been buried long ago.

The issue of how to make sense of the complex world we inhabit seems to be a recent instance of this phenomena.

It is not a new issue by any means, and has haunted humans ever since we’ve evolved the gift of reason.

One of the big branches of philosophy is dedicated to this problem, which can be stated as how to separate right from wrong, or rather truth from non-truth?

More simply: how do we know things, and what does knowledge look like?

This branch goes by the eerie name of Epistemology, started by the Greeks.

Arguments in this philosophical tradition are of surprising complexity, and are tough to mingle with, dating back to the likes of Plato, Aristotle and the pre-Socratics. A can of worms awaits those brave enough to dedicate their energy to exploring its full glory.

But why should you, or anyone? Well, the discussions are of crucial importance to deciding how to pick beliefs from the endless stream of stupid ideas in your head and others’.

And beliefs are what determine your decisions and behavior. Truthful beliefs produce good decisions, and good outcomes. False beliefs will lead you (and entire nations with you) to error and tragedy.

The good news is, you don’t have to start from a tabula rasa. A host of brilliant individuals have left a trail of breadcrumbs (more like a high-res map) that leads to the consensus that has allowed our ancestors to build the modern world and all of the jaw-dropping wonders of it: the scientific method.

It dictates that nature is the final judge of truth, and that ideas are nothing more than worthless hypothesis, unless relentlessly tested against objective reality, repeatedly and by different people.

It is clear to anyone that glances over the trajectory of humankind that things really started picking up since we started using this to determine valid knowledge. As such, the proof is in the pudding (and in the Moon), and anyone would be hard-pressed to dispute the efficacy of good science.

Given its accomplishments, you’d think that such a framework would be constantly celebrated, to the likes of having monuments erected in its homage, and all children being force-fed it through schools’ curricula, being denied further advancement until demonstrating their skill in applying it over and over again.

And although some of that does happen, it isn’t nearly to the extent that you would expect in the Western world, its birth-place. And regular folk still seem pretty lousy at it.

The reason for that lies in the 20th century.

Justified fear of deterministic convictions arising have since led to a sort of downplay of the effectiveness of science, and a post-modern relativistic interpretation of reality.

This, in turn, has allowed mysticism and pseudo-scientific hogwash to make a comeback. Which has made people dumber and confused.

Science also acquired a bad rep in the collective memory as the image of an ascending mushroom cloud.

Let‘s be clear though: evil and malice are separate from the scientific method, which is, by definition, morally neutral. The mushroom cloud is at the same time both a testament to science’s cold efficacy, and to the dark human potential for destruction.

But humans also have the potential for good and virtue (which is less often remarked on), and there are just as many — arguably much more — virtuous stories of scientific accomplishment. These should be celebrated more often, especially since their graces adorn our every waking moment, and routinely save the lives of the people we love.

Good science makes a person free, competent, hard to manipulate and withholding of judgement and prejudice.

A lack of a decent framework to guide our critical thinking, on the other hand, leaves people facing a terrifying abyss of subjectivity, and is definitely related to the alarming rates of depression and anxiety in Western society. Let alone the results of misguided decisions and public policy.

History is full of examples of horrors that could’ve been avoided if we had the proper knowledge at hand, and just weren’t so ignorant (e.g. doctors not washing their hands prior to surgery).

It is important to know what science is and isn’t. It is not a source of spiritual meaning, or answers on morality or the value of human life.

It is, instead, a damn fine tool for making all that virtue manifest, should you care to master and apply it.

And you should.

Unexpressed, the particular richness of a life is lost in the mall of generic memory.
