I was on the NRO website a few months back, and I read that they had a few copies of William F. Buckley's book, "Keeping the Tablets" for sale.
It is a collection of essays on Conservatism. I owned the books several years ago, so I thought I'd buy one and read it again.
Lucky me, it was an autographed copy.
In the preface, Buckley stated that conservatism is sometimes difficult to describe. He noted that even at NR, many of the conservative writers there would take opposite sides of a position, and lay out cogent arguments on how their individual opinions were considered conservative.
This book also had some examples of that very thing. The NR crowd running off the John Birchers is another prime example.
As far as Buckley goes, I am sure he felt his brand of conservatism was the right way. No one can deny that he espoused his believes eloquently, and always well thought out.
Now, having said all that, I'd say the first tenet of what we now call conservatism, at least, American conservatism, is private property rights, which was a huge deal for our founding fathers.
Also, add in the Declaration of Independence and the Bill of Rights.
Finally, the things conservatives are trying to "conserve" are time-tested traditions and institutions that work, and have a history of proven results.
As we all here at TBR know to be true (in this order):
Finish School.
Start a career and work hard.
Get Married and stay married and faithful.
Have Children.
Do these things in correct order and the odds of being poverty-stricken are greatly reduced.
The Bible teaches us to do the exact same things, and a lot more.
Just my 2 cents (plus inflation) worth....
