Nothing Occurs at Random

This week I have come across a pre-Socratic Greek philosopher named Leucippus. According to Wikipedia, he "is credited with developing the philosophical school of atomism. He proposed that all things are made up of microscopic, indivisible particles that interact and combine to produce all the things of the world." He developed this theory with his student Democritus, in the 5th century BCE.

But the Wikipedia article is careful to point out that there are great differences between Leucippus's 'atomism' and modern atomic theory: "Instead of the purely material atoms of Leucippus, modern atomic theory shows that fundamental forces combine subatomic particles into atoms and link atoms together into molecules."

In his work, On Mind, he wrote, "Nothing occurs at random, but everything from reason and by necessity." Yet at the same time, he rejected the idea that there was an intelligent force (or deity) controlling the universe.

I'm not sure I agree with him. "Nothing occurs at random, but everything from reason and by necessity." In which case, where does free will fit in? If everything occurs "by necessity", then what difference can we, as human beings, make to the world? 

I would rather believe that, although there are many forces at play in how events in our world come to pass, nevertheless, the actions of individual human beings can make a difference. There is a theory that a small stone, placed in exactly the right place in a river, can change the course of that river. In human terms, the actions or words of a single person, done or said at exactly the right time, can change the beliefs of a whole society, its awareness of a particular situation that people have (up until that point) accepted unthinkingly. For example, Rosa Parks sitting down on a bus, and refusing to get up because a white person wanted her seat, is an example of one small action ultimately making a huge difference.

So I believe that it is possible to make a positive difference, by our actions and words. That nothing is inevitable, although I completely understand why things may seem to be so. It takes a lot of courage to go against the accepted flow of one's society, to stand up for the possibility of a new and better way of doing things, a new and better way of human interaction.

I suppose that the second part of Leucippus's quote may cover this: that "everything [occurs] from reason"... so it is when a person (or people) use their innate reasoning powers and come up with new understandings of the world, that change becomes possible.

Or, just possibly, it is when a person listens to the "still small voice" of their conscience, or of God inside them (depending on your beliefs) that they become able to grow and change and interact with the world around them in a more positive way.

To conclude, while we may believe that nothing occurs at random, there are very many forces at work in the world, which influence the things which do occur, including human free will, reason, and conscience.
