The upshot is that most philosophers of biology now hold that biological properties supervene on physical properties (where supervenience is taken to include some kind of "in virtue of" relation), and that fitness and other biological properties are not identical with physical properties.

Elliott Sober

Art really is something very difficult. It is difficult to make, and it is sometimes difficult for the viewer to understand. It is difficult to work out what is art and what is not art.

Anselm Kiefer

Consider that spiritual safety comes through spiritual unity. Christians united together are difficult to separate, difficult to break, difficult to pick off and destroy. It is when you isolate yourself by disrupting or denying unity that you are most at risk.

Thomas Brooks

The reason why access to facilities - and access to public spaces - is so important is because it's much more difficult to go to work, to go to school, to participate in the public marketplace if you can't access bathrooms that make sense for you, that match who you are.

Sarah McBride

We have altered the physical, chemical and biological properties of the planet on a geological scale. We have left no part of the globe untouched.

David Suzuki

I also assume that they are not simply the physical properties of things as now conceived by physical science. Instead, they are ecological, in the sense that they are properties of the environment relative to an animal.

James J. Gibson

...many have the idea that organizing people is very difficult, but it isn't. It becomes difficult only at the point where you begin to see other things that are easier. But if you are willing to give the time and make the sacrifice, it's not that difficult to organize.

Cesar Chavez

I'm afraid my own approach to everything is exactly the same: Who am I? What do I want? What are the circumstances - difficult or non-difficult? What are the obstacles, physical and non-physical? Finally, given who I am, the circumstances, the obstacles, what do I do? That's the only thing you do. You've got to do the action.

Prunella Scales

It's very difficult to break in Europe unless you break in England, and it's very difficult to break in England if you're Irish.

Dolores O'Riordan

We are difficult. Human beings are difficult. We’re difficult to ourselves, we’re difficult to each other.

Geoffrey Hill

Any attempt to reduce the complex properties of biological organisms or of nervous systems or of human brains to simple physical and chemical systems is foolish.

Kenneth E. Boulding

The well-known fact that the form of a specific substance, e.g. water, and hence its properties can alter without a change in composition was disposed of by the formal view that a physical, not a chemical, process was involved.

Wilhelm Ostwald

This is about doing something difficult and not stopping when it becomes not just difficult, but cold and difficult...or cold and wet and difficult...or cold and wet and dark and difficult.

Suzy Favor Hamilton

It's difficult to make your clients understand that there are certain days that the market will go up or down 2%, and it's basically driven by algorithms talking to algorithms. There's no real rhyme or reason for that. So it's difficult. We just try to preach long-term investing and staying the course.
