Inertia Quotations

Total physical and mental inertia are highly agreeable, much more so than we allow ourselves to imagine. A beach not only permits such inertia but enforces it, thus neatly eliminating all problems of guilt. It is now the only place in our overly active world that does.
John Kenneth Galbraith

Though we may never be able to comprehend human life, we know certainly that it is a movement, of whatever nature it be. The existence of movement unavoidably implies a body which is being moved and a force which is moving it. Hence, wherever there is life, there is a mass moved by a force. All mass possesses inertia; all force tends to persist.
Nikola Tesla

I don't think we're yet evolved to the point where we're clever enough to handle a complex a situation as climate change. The inertia of humans is so huge that you can't really do anything meaningful.
James Lovelock

If you work hard in real life, people tend to get in your way - either from inertia or prejudice - and they stop you achieving things. It's the worst thing about real life compared with sports, where you generally get what you deserve: if you're the fastest guy, you win; there are no other games being played.
Daley Thompson

The reason men oppose progress is not that they hate progress, but that they love inertia.
Elbert Hubbard
