@mossfitz Yes, I understand. But highlighting "rather" - this is "exclusive OR". Rationality and logic mainly intersect, so selecting the "exterior" category seams odd. There are lots of rational illogical statements, however "one must learn to think rationally rather then logically." seams a bit extreme.
@Mattprole: At last, someone is speaking it out loud. Thanks for that. There are too many people around with "theories" who don't have the slightest clue about even the basics of physics. That's the backside of Youtube. 20 years ago those people were just some weirdos who printed their own books at home and sold them via snail mail to other weirdos. :)
Penrose talks about the holding of contradictory ideas at the same time as if that's something profound, but that practice has been around for eons, and was likely used by very primitive humans. I suspect some animals can do that too.
The thing with "Road to Reality" is that there's an awful lot of math... but is presented so skillfully, and is so interesting, that you end up feeling you HAVE to learn the math to see "what's going on". By the fifth or sixth chapter you're knee deep into toe-to-toe combat with complex analisys, but you would give up trying to figure out the math (and thus understand the concepts) even if your life depended on it. Believe me, it's that good!
@signorellil: Absolutely. Penrose's achievement is that you can enjoy the book even if you understand only 10% or less of it. He's an amazing writer. And the mathematical problems in the footnotes with those funny symbols for different degrees of frustration you would get solving them - plain genius.
Penrose is one of the most important physicists working today, because he is willing to look out outside the box.

@alexeevic Joyce´s "Do i contradict myself? Very well, i contradict myself." is hardly logic - but is of course rational.

Penrose books don't insult our intelligence. It presents us with the maths that are entirely necessary for genuine comprehension of the sciences.

How are you going with the maths ?

I struggle with the maths in some places. But I think I get the physics. Thanks for the reply

Considering if you're wrong isn't sidestepping reason, that IS reasoning.. same with looking at both sides of a position.
