An intelligent person is someone who, when all others follow the crowd in believing that something is fake, decides to investigate and see whether or not it is true or untrue, and then at least, you can know by direct experience, as opposed to just following the general consensus, like 99% of people do. ''Astology is fake'', okay how do you know that?, ''uh because it just is'', alright okay. Some of the most intelligent people of all time believed in funny ideas: William Blake, Swedenborg, and Crowley among others. Its okay to think something might exist, what are you afraid what people will think of you?, insecure are we?. My sign is Virgo and i have found that Sagittarius and Gemini are also quite intelligent, i'm not saying all of them, but the ones in my life. So keep an open mind and see if something is true or not.
