A thing is only itself when it is doing nothing; as long as it is doing something it is its own tool and not itself.

Context

“Our body is our tool-box—and our bodily organs are the simplest tools we can catch hold of. When the amœba has got the piece of meat and has done digesting it, it leaves off being not itself and becomes itself again. A thing is only itself when it is doing nothing; as long as it is doing something it is its own tool and not itself. Or you may have it that everything is itself in respect of the pleasure or pain it is feeling, but not itself in respect of the using of itself by itself as a tool with which to work its will. Or perhaps we should say that the ego remains always ego in part;” source
