On the heels of his new book release, entrepreneur Peter Thiel has social media buzzing. The co-founder of PayPal and software company Palantir, Thiel isn't known for being shy--he's voiced opinions on everything from startups to politics to (yes, even) robots. As recently as Friday, he sounded off in a debate with professor David Graeber, discussing everything that he thinks America is getting wrong. 

In the spirit of the times, here's a roundup of some of our favorite Thiel-isms to date:

1. "Twitter is hard to evaluate. They have a lot of potential. It's a horribly mismanaged company--probably a lot of pot-smoking going on there." 

--In an interview with CNBC last week, Thiel ranted against the social media giant. 

2. "University administrators are the equivalent of subprime mortgage brokers selling you a story that you should go into debt massively, that it's not a consumption decision, it's an investment decision. Actually no, it's a bad consumption decision. Most colleges are four-year parties." 

--Thiel has controversial views about higher education, which he shared with the Wall Street Journal.

3. "I no longer believe that freedom and democracy are compatible." 

--He's also open about being a Libertarian, writing for the debate journal Cato Unbound.

4. "There are still many large white spaces on the map of human knowledge. You can go discover them. So do it. Get out there and fill in the blank spaces. Every single moment is a possibility to go to these new places and explore them." 

--Masters guest posted 10 key lessons from Thiel's course on startups in Forbes. 

5. "Consider the trivial but revealing hallmarks of urban hipsterdom: faux vintage photography, the handlebar mustache, and vinyl record players all hark back to an earlier time when people were still optimistic about the future. If everything worth doing has already been done, you may as well feign an allergy to achievement and become a barista."

--In his book, Thiel laments society's lack of interest in discovering new secrets. 

6. "The preference I have for startups rather than large movements is that you have to convince a much smaller group of people...that the future can look very different." 

--He touched on a variety of topics--including the benefits of small business--in Friday's debate with Graeber, as reported by Inc.

7. "This is always a problem with elites, they're always skewed in an optimistic direction." 

--Thiel opened up about his views on the upper class in a November 2011 interview with The New Yorker.

8. "I think one of the most contrarian things one can do in our society is try to think for oneself." 

--He sat down with the Financial Times last year and made a series of characteristically big claims. 

9. "I'm short on New York, long on Silicon Valley."

--He's not confident that New York will continue to be the dominant American city for much longer, he discussed in an interview with Alexia Tsotsis at TechCrunch Disrupt 2014. 

10. "It's very hard to get reasonable science, reasonable technology policy when people understand these areas as poorly as they do in D.C...The rest don't understand that windmills don't work when the wind isn't blowing or that solar panels don't work at night--they're sort of in the Middle Ages." 

--He sounded off in an interview with the Wall Street Journal'Dennis Berman at the WSJD Live Global Technology Conference in October 2014.
