A Few Principles for Thinking Clearly

Read widely, with maximum curiosity

The clearest thinkers tend to be those that draw from multiple disciplines.

Develop the habit of reading and eliminate/reduce the things that might stop you from doing that (e.g. mindless TV watching or checking social media constantly).




Components of a good essay

Many people think a good essay is persuasive. But more importantly, an essay should be useful.
There are four parts to a good essay:

  • correctness
  • strength
  • importance
  • novelty

An essay should be correct. However, to be correct is not enough if it is vague. 

Don't publish anything unless you're sure it's worth hearing. Write the first draft of an essay quickly, trying out all sorts of ideas. Then rewrite it very carefully, being sure to sift out anything that you're not sure of, or that is not true. Useful writing makes claims that are as strong as they can be without overstating it.


Strength comes from two things: thinking well, and the skillful use of qualification.

Qualifications can express many things: how broadly something applies, how you know it, how happy you are it's so, even how it could be falsified. As you try to refine the expression of an idea, adjust the qualification accordingly. The more you refine an idea, the less you'll need to qualify it. However, don't underestimate qualification. Learn to use its full range.

Iron: the fourth most abundant element on earth
Iron: the fourth most abundant element on earth

Iron is the fourth most abundant element in the Earth's crust, and is found as an ore called Magnetite. Iron is crucial for creating steel, which is required for countries which are undergoing industrialization.

While we humans mine a lot of sophisticated metals like Aluminum and Titanium, Iron forms the skeleton of modern infrastructure.

The early history of iron exploitation

Iron has been collected, mined and processed into its metallic form since 1200 BCE. Large scale production only started in 1750, at the start of the Industrial Revolution.

Steel, an alloy of Iron and Carbon is known for its purity and strength, and was patented by British inventor Sir Henry Bessemer in 1857. Steel helped humanity make stronger and larger tools, paving the way for industrialized progress.

Iron and the increased demand for wood

Scaling up of iron production in Great Britain, the birthplace of the Industrial Revolution, led to a dramatic increase in the demand for wood. The creation of steel takes its toll on forests, with the requirement of charcoal, a residue of wood, to smelt iron and carbon.

Charcoal production, leading to demand for wood, has since then led to widespread deforestation with thousands of square kilometers of forests cut annually.
