Lisp is a programmable programming language. -- John Foderaro

Since programmers create programs out of nothing, imagination is our only limitation. Thus, in the world of programming, the hero is the one who has great vision. Paul Graham is one of our contemporary heroes. He has the ability to embrace the vision, and to express it plainly. His works are my favorites, especially the ones describing language design. He explains secrets of programming, languages, and human nature that can only be learned from the hacker experience. This book shows you his great vision, and tells you the truth about the nature of hacking. -- Yukihiro "Matz" Matsumoto, creator of Ruby

Any sufficiently complicated C or Fortran program contains an ad hoc, informally specified, bug-ridden, slow implementation of half of Common Lisp. -- Philip Greenspun (Greenspun's Tenth Rule)

This challenge, viz. the confrontation with the programming task, is so unique that this novel experience can teach us a lot about ourselves. It should deepen our understanding of the processes of design and creation, it should give us better control over the task of organizing our thoughts. If it did not do so, to my taste we should no deserve the computer at all! It has allready taught us a few lessons, and the one I have chosen to stress in this talk is the following. We shall do a much better programming job, provided that we approach the task with a full appreciation of its tremenduous difficulty, provided that we stick to modest and elegant programming languages, provided that we respect the intrinsec limitations of the human mind and approach the task as Very Humble Programmers. -- E. W. Dijkstra, The humble programmer

Genius is 1% inspiration and 99% perspiration. -- Thomas Edison

Abstraction is a form of data compression: absolutely necessary, because human short-term memory is so small, but the critically important aspect of abstraction is the algorithm that gets you from the name back to the "uncompressed" details. -- Bruce Wilder (blog post comment)

Limitations live only in our minds. But if we use our imaginations, our possibilities become limitless. –Jamie Paolinetti

The distance between insanity and genius is measured only by success. ~Bruce Feirstein

When I stand before God at the end of my life, I would hope that I would not have a single bit of talent left and could say, I used everything you gave me. –Erma Bombeck

If you want your children to turn out well, spend twice as much time with them, and half as much money. –Abigail Van Buren
