Although a lot can be said and discussed about the same, a very simple and straight forward answer comes to my mind.
By critical thinking alone!
The following excerpts from Feynman’s lecture in Physics say it all.
“A poet once said, ‘The whole universe is in a glass of wine.’
It is very true.
Look at a glass of wine closely enough to see the entire universe.
- the twisting liquid which evaporates depending on the wind and weather, the reflection in the glass; and our imagination adds atoms.
- a distillation of the earth’s rocks, and in its composition we see the secrets of the universe’s age, and the evolution of stars.
- a strange array of chemicals in the wine? How did they come to be?
- the ferments, the enzymes, the substrates, and the products.There in wine is found the great generalization; all life is fermentation.
Divide this glass of wine, this universe, into parts — physics, biology, geology, astronomy, psychology, and so on to all other branches of knowledge.
Remember: Nature does not know it!
Each one of has to think and learn on his own. After all Science has its origin and existence only in our ability to think and analyze.
Enjoy: drink wine; throw the glass and forget it all”.
THE MESSAGE IS LOUD AND CLEAR.
No thinking! No Science!
Listen to the message in this melodious style!
