ANYONE CARE TO HELP

I already have three tattoos (one on my lower back, right ribcage, and right foot) and Im proud to say I designed them all and that they all have meaning......I am a philosophy major and I am fasinated with Rene Descartes who famously said "I think therefore I am" or in latin "cogito ergo sum".....I want to get a tattoo with that famous quote included however I am drawing a blank......Nothing too big and detailed just something simple that reflects the quote and is feminin yet interesting......does anyone have ANY suggestions???

He was also a mathematician right? maybe something with numbers and equations, he also wrote some things on human nature and even delved into the metaphysics. Maybe i'm getting the wrong idea about the tattoo you're wanting but if it's a Rene Descartes tattoo you're after your options aren't limited to just a quote and some numbers, the man had an idea about everything. I think it'd be real neat to hear some more of your ideas on how you'd like to see this tattoo of your's completed. On something like this I do think it'd be wise to design your own unless you find a competent artist with the same passion for philosophy as you and i'm sure you could. Or if you do choose to have the artist draw you some custom pieces , just get your ideas together in how you'd like it to look or what images and emotion you'd like the finished product to convey. You've already stated you want it feminine that's a start.
