I define UNIX as 30 definitions of regular expressions living under one roof.
In our daily lives as programmers, we process text strings a lot. So I tried to work hard on text processing, namely the string class and regular expressions. Regular expressions are built into the language and are very tuned up for use.
There are definitions of morbid obesity. Doctors define it.
The government of India is consistently very advanced. When the world was hesitant on UNIX, we were the first to move in; the RBI said that all banks will implement on UNIX. It worked!
We use the official definitions of terrorism. The definitions in the U.S. code, in British law, in U.S. Army manuals and so on. And if you use those definitions it follows instantly that the United States is the leading terrorist state in the world.
I define a diva as a woman who possesses courage, beauty, style, and confidence. Based on that definitions, I've probably got a bit more work to do.
GNU, which stands for Gnu's Not Unix, is the name for the complete Unix-compatible software system which I am writing so that I can give it away free to everyone who can use it.
I must say the Linux community is a lot nicer than the Unix community. A negative comment on Unix would warrent death threats. With Linux, it is like stirring up a nest of butterflies.
Euphonic and harmonious expressions, forcible and just expressions, profound and comprehensive expressions, and especially apt and witty expressions, each have their specific influence upon different minds, and their common influence upon all minds.... It is therefore high time our most valuable aphorisms and paragraphs were put in order for frequent perusal, and for handy reference, as the circumstances of life call up subjects.

If we could all give our own definitions of God, there would be as many definitions as there are men and women.
One should not be too distracted by definitions. Ideas transcend definitions.
If you're interested or like it, but could be just as happy living in a regular town, having a regular job, maybe doing little theatre, you're better off and you'll be a happier person. This is too gut-wrenching and heartbreaking.
In other words, the propositions of philosophy are not factual, but linguistic in character - that is, they do not describe the behaviour of physical, or even mental, objects; they express definitions, or the formal consequences of definitions. Accordingly we may say that philosophy is a department of logic. For we will see that the characteristic mark of a purely logical enquiry, is that it is concerned with the formal consequences of our definitions and not with questions of empirical fact.
Our scientific age demands that we provide definitions, measurements, and statistics in order to be taken seriously. Yet most of the important things in life cannot be precisely defined or measured. Can we define or measure love, beauty, friendship, or decency, for example?
