Scientific Progress Consists In The Development Of

The Most Consequential Change In Man's View Of The World, Of Living Nature And Of Himself Came With The Introduction, Over A Period Of Some 100 Years Beginning Only In The 18th Century, Of The Idea Of Change Itself, Of Change Over Periods Of Time: In A Word, Of Evolution.

The Issue, As Correctly Emphasized By Carl Sagan, Is The Probability Of The Evolution Of High Intelligence And An Electronic Civilization On An Inhabited World. Once We Have Life (and Almost Surely It Will Be Very Different From Life On Earth), What Is The Probability Of Its Developing A Lineage With High Intelligence? On Earth, Among Millions Of Lineages Of Organisms And Perhaps 50 Billion Speciation Events, Only One Led To High Intelligence; This Makes Me Believe In Its Utter Improbability.

Mathematics Is As Little A Science As Grammar Is A Language.

Evolution ... Is Opportunistic, Hence Unpredictable.

In Neither His Definition Nor The Examples Illustrating What Memes Are Does Dawkins Mention Anything That Would Distinguish Memes From Concepts.
