"All things are possible until they are proved impossible - and even the impossible may only be so, as of now"

Human understanding, innovation, and achievement are often limited not by the actual laws of nature but by the boundaries of current knowledge. The assertion that all things are possible until proven otherwise is a powerful testament to curiosity and the ever-evolving nature of discovery. It challenges everyone to regard boundaries not as final verdicts but as temporary markers awaiting further inquiry and vision.

Throughout history, what was once deemed impossible has been overtaken by new methods, technologies, and paradigms. Flight, exploration beyond Earth's atmosphere, curing diseases, even communicating across continents instantly–these were fantasies or impossibilities for centuries and are now woven into daily life. Pearl S. Buck’s message resonates as a call to suspend disbelief, fostering a mindset that is open to the unexpected and unimagined. The idea that the impossible exists “only as of now” encourages appreciation for the fluidity of progress, reminding us that certainty is often only provisional, defined by present perspective, tools, and knowledge.

Progress depends on individuals willing to challenge what is assumed, to pursue lines of inquiry that disrupt comfort and embrace uncertainty. The phrase invites a sense of humility; it demands recognition of how little can be known with absolute certainty and invites flexibility in thought. This openness lays the groundwork for creativity, risk-taking, and perseverance in the face of doubt or skepticism. There is a subtle optimism and profound responsibility implied, the duty to doubt perceived limitations and venture further, intellectually or materially.

Ultimately, the essence of Buck’s words is both a celebration of human potential and a sober reminder to avoid dogmatism. Today’s impossibilities might crumble tomorrow in the face of fresh evidence, relentless effort, or a simple shift in perception. Maintaining an attitude that hovers at the threshold of what is known and what is possible is the soil in which progress flourishes.
