4 minutes of leisurely exploration.

January 15, 2025 Edition

1START: Philosophy >

The race to Mars is ambitious, but it’s not a shortcut to saving humanity. Real innovation and the next steps beyond Earth clearly lie with a network of space stations—something NASA is quietly pursuing. If we can’t sustain life in isolated space stations, how can we hope to thrive on a barren, hostile planet?

Does Musk’s Mars vision highlight poor reasoning?

2Science >

Play evolved as one of the group survival traits. Lower play abilities evolved in mammals like rodents about 190 million years ago. Higer play abilities evolved in mammals like cats about 80 million years ago.

When did play evolve in mammals?

3Critical Thinking >

Our search for alien life isn’t just a journey through space—it’s a challenge to overcome cognitive biases like anthropocentrism and confirmation bias. Critical thinking helps us see beyond our own assumptions and embrace the true vastness of possibility.

CRITICAL THINKING: Does the Fermi paradox lack good thinking?

4History!

In ancient Greece, as sophia and sophist became associated with rhetorical trickery, the terms philosophy and philosopher emerged to reclaim the pursuit of wisdom and truth.

Did Pythagoras coin the word philosophy?

Quote of the Week

Philo Quote, “…allegories…lay hold of the hidden sense which is concealed beneath the words”

Philo of Alexandria
circa 20 CE

Allegorical Interpretation

TAKE-AWAY: An allegory is a literary technique in which the writing represents deeper meanings than the words might initially imply. Allegorical interpretation is the process of understanding the symbolic meaning behind a text or story. It allows for a deeper understanding embedded in literature, art, and movies.
