Aphorisms and Idioms: Nothing In Life Is To Be Feared, It Is Only To Be Understood

N
othing in life is to be feared, it is only to be understood. Spoken by one of history’s greatest scientists, Marie Curie’s timeless words continue to inspire people across generations.

Curie’s quote points out that all too often, fear comes from a lack of knowledge. Whether it’s rooted in fear of the unknown, or an insufficient understanding of something we find fearful. So, she encouraged folks to ask questions and seek knowledge rather than allowing fear to control our lives.

Because our fears often fade when we replace the uncertainty that sparks them with knowledge, and unfounded assumptions with understanding. This aphorism speaks to  education’s capacity for conquering ignorance and building a better future.[1]

Who Is Marie Curie?

Marie Curie was an early 20^th century chemist and physicist, best known for her groundbreaking research on radioactivity (a term she coined).

She was the first woman to be awarded the prestigious Nobel Prize.  And made history again by receiving the Nobel Prize in Chemistry, becoming the first person to win the Nobel Prize in two different scientific fields.

Curie’s relentless pursuit of knowledge genuinely transformed the world. And her trailblazing research continues to influence it. Curie’s work laid the foundation for critical advances in physics, chemistry and medicine – including the development of radiation therapy, which is used for cancer treatment.[2]

Her advice is as relevant today as it was over a century ago. Because books revolving around stories that reflect diversity, equality and inclusion (DEI) are being heavily targeted for the banning we see so much of these days.

As a result of book banning, students are being denied the opportunity to learn about people whose lives may be different than their own. And whether it’s intentional or not, banning books that reflect diversity suggests to students there is something to be feared about the communities whose stories are being stricken from libraries, classroom shelves, and curriculums.

So, seek knowledge rather than allowing fear to control your life. Learn about cultures other than the one you grew up in. Read about people whose lives are different than your own. And make sure your student does the same. Because nothing in life is to be feared, it is only to be understood.
