Every essay in this book is so well constructed, and elegantly written.
Of course some are more intricate than others, but those complex essays are only so due to the complexity of their respective topics. A discussion on the cosmos is going to be far more demanding than a discussion on environment and pollution.
There is some redundancy throughout this book, due mostly to the independency of each article written by its author, namely the professional in that particular field. Truth is, however, with such world-altering ideas, perhaps a little redundancy can be beneficial.
Overall, I thoroughly enjoyed this book as a cerebral piece. I do not struggle with faith in the Torah, but it's nice to see each and every argument in its favor crafted so beautifully and constructed in a way that can be relayed or debated with another. Sometimes we know why we believe what we believe but find it difficult to find the right words. This book does just that - it provides the words and arguments we laymen so often lack.
