Viktor Frankl, Author,

one of my favorite books was by a psychiatrist who actually wrote a more psychological book,
Viktor Frankl, read his book The Will to meaning, can't remember the three pillars he said our push forward in life is comprised of, amazing book, the guy had such a massive concept in this book,
I felt as I read it like I was trying to walk on the water but my feet barely got traction of his concepts, found it difficult to really dig in, like i was just skittering along the top without being able to really dig in,

much greater intellect than say a Farheed Zakaria, read part of one of his books, didn't really get into it,
if you want real deep meaningful intellectual books try Viktor Frankl,
