I am not a fan of sealed up sterile homes or Faraday cages and their use in human health, although I do understand that some people do feel relief in these environments.

Perfection seems sterile; it is final, no mystery in it; it's a product of an assembly line.

Living in sterile man-made environments that are disconnected from nature should be expected to lead to sickness.

Time... is an essential requirement for effective research. An investigator may be given a palace to live in, a perfect laboratory to work in, he may be surrounded by all the conveniences money can provide; but if his time is taken from him he will remain sterile.

My mind is like a racing engine, tearing itself to pieces because it is not connected up with the work for which it was built. Life is commonplace; the papers are sterile; audacity and romance seem to have passed forever from the criminal world. Can you ask me, then, whether I am ready to look into any new problem, however trivial it may prove?
