Our planet has been home to countless billions of people throughout time. However, few have managed to leave their mark or contribute to the role and place of humanity more than scientists with their discoveries, inventions, and revolutionary thinking. Much of these people’s impact can be noted in their brilliant and powerful quotes. Our quest as a species has been and continues to ultimately be twofold: to find out who we are as individuals (self-discovery) and what our station is in the grand scheme of the natural world and the cosmic. For some, this may include a search for a higher power. On the other hand, others seek to understand the intricacies of nature and the cosmos.

In fact, their quotations alone have been enough to inspire others to change their lives for the better. From Socrates and Aristotle to Albert Einstein and Carl Sagan, these are 25 Powerful Quotes From Scientists That Are Truly Thought-Provoking.
