Here’s a surprisingly useful thinking tool for anybody interested in the history of Western philosophy: a sort of garden of forking paths of argument. https://t.co/AH1ophVXH8

A stunning, interactive visualization of the history of philosophy by @denizcemonduygu, showing the positive and negative connections between some of the key ideas and arguments from philosophers https://t.co/vHvluivXsM

Love this interactive timeline of philosophical ideas. Not only to you get the ideas, but linkages showing who agreed/disagreed with whom.https://t.co/y2H0j2LmbA

This is my summary of the history of (Western) philosophy showing the positive/negative connections between some of the key ideas/arguments/statements of the philosophers. It is not an automated text analysis project; the content and the connections are the result of my years of reading and taking notes, so it’s a never-ending work-in-progress. It started with Bryan Magee’s The Story of Philosophy and Thomas Baldwin’s Contemporary Philosophy as the main references but it keeps expanding with dozens of others. (The reference is noted with the book icon that appears when you click on a statement.)
First off, let me announce that though I read my share of philosophy and have a good grasp of the fields/philosophers I’m interested in, I’m not a historian of philosophy. This is a purely personal project that I’m doing in my own time, with my limited knowledge, for myself; and I’m sharing it to get feedback and to make it accessible to those who are interested. As much as I find this way of looking at philosophy productive (and fun) for many reasons, I’m not proposing that this is the right way to look at it; it is just one version that I like to see – an organized collection of notes, reminding the arguments and letting me see how they developed, from a distance. I like to think that it’s not just a historical project, useful for people specifically interested in the history of the field; what is also valuable here is the ability to see, by clicking on a sentence and displaying its connections, what different things can be said on a subject (how many perspectives there can be, which are hard to be all dreamed of by a single person) independently of who said them and when – independently of a direct interest in the history of philosophy.
What exactly am I doing? When I’m reading the texts, I’m summarizing argumentations with isolated sentences. In the next step, I’m optimizing them so as to include all of their ideas with the minimum number of efficient sentences, in a meaningful order. (I usually shorten/paraphrase the sentence if it’s coming from a secondary source like a book of history of philosophy, but I try to quote it as it is – as long as it’s not too long – if it’s from the philosopher.) Then I’m noting the positive/negative connections to other statements, putting all this information in a spreadsheet in a machine-readable format, going through everything to look for further possible connections, and finally feeding it to the visualization. If a statement agrees with or expands on an old one, they’re connected with a green line. If it disagrees with or refutes an old statement, they’re connected with a red line. Some of these connections are explicitly described by the philosophers or the historians, some of them are drawn by me.
Maybe you can complain that I have low standards for a connection in general. The question always arises: “Clearly these two statements are talking about the same thing, but did he really read that old guy, or did he come up with it all by himself?” Except for a few specific cases, I ignored this question for two reasons. First, most philosophers read most people before themselves and they don’t always add extensive lists of names/references for every argument they produce; so I usually assume there may be a direct connection even though it’s not written somewhere. (You could make a version with only the connections confirmed by the philosophers/historians, but that would be too boring for my taste.) Secondly, and more importantly, the fact that there may not be a direct reference (written or not) doesn’t spoil my concept of connection here: when I’m drawing a line I’m not always claiming that the philosopher directly took the idea from the connected philosopher. The lines here do not always depict a direct transfer between two people; I think of them as tracing the development and the diversification of ideas throughout time, connecting different perspectives on a subject. This choice is also evident in the non-directionality of the connection lines: the direction of a possible direct transfer is obvious when there are dozens of years between two philosophers, but for those who live and write during the same years, it is quite possible that they take ideas from each other, get in conversations, etc. In that broad sense I’m confident that these connections make sense but I may of course be mistaken with some of them; please warn me if you think so.
I am of course aware that not everybody is here and the arguments-connections of the included philosophers aren’t exhaustive. I am also aware that the level of detail isn’t the same for every philosopher. The content for some philosophers are more beginner-level because they come from books intended for general audiences, and some philosophers have more detailed and extensive content because I had the opportunity to concentrate on them by reading multiple documents, sometimes including their own output. My goal is to slowly go through everybody so as to keep a somewhat homogeneous depth overall – this is a continuous effort which will proceed in parallel with the work of adding new names. I don’t think this project can ever be “completed”, but I will be expanding it by adding information from everything I read – maybe until I die – in the hope of making it as complete as I can. And yes, I may be prioritizing philosophers/schools/subjects I like in the process. I’ll also be adding more thinkers who aren’t strictly “philosophers” but had considerable effect on philosophy (like Darwin, Freud, Turing, etc.) and philosophers from other traditions. So please don’t get angry if your favorite philosophers or ideas aren’t here: this is not a finished product, and they probably are in my to-add list. You can see the list of updates on the Updates page where you can also subscribe to get notification emails when I add new content or make interface upgrades. (Some people proposed that I switch to a collaborative content creation model – I have no intention of doing that, although I’m fully open to corrections and suggestions from philosophers or historians of philosophy.)
One warning: Browsing this visual summary cannot substitute reading a good book of history of philosophy, let alone reading the original texts by the philosophers. These sentences are dry summaries of long, intricate argumentations and some of them are not even comprehensible if you’re not already familiar with the subject/philosopher. Some of these ideas are best understood within the historical/political context, as they are presented in books of history of philosophy. So no, you shouldn’t expect to learn philosophy by just using this summary. As I wrote in the beginning, this is an organized collection of notes to myself, and I believe it can have this function for other people who have read some history of philosophy as well. (I also believe it can function as a teaser for people who aren’t familiar with the field, making them feel curious about an idea/discussion and start reading about that.) As Baldwin reminds,
“[C]ontemporary philosophy is dialectical in its method: new arguments necessarily make reference back to earlier positions which provide the background for understanding the commitments which the arguments seek to challenge. (…) The relation of present arguments to past debate provides by itself good enough reasons for regarding the continuation of such debates as the only way of improving our understanding.”
I conceived this project in February 2012 while organizing my notes from my readings (“There should be a global and systematic way to see all these relations! How about…”) and started working on it in February 2014.
I also thank my friend Eser Aygün for writing the program that automatized to a great degree the transition between the spreadsheet that I fill in and the visual end-product for the static version in the beginning of this project.
And here are the names of nice people who offered content corrections or improvements that I was able to apply so far: Sedat Hasoğlu, Jakub Rudnicki, Matheus Schneider, César Tomé López, Sylvia Wenmackers, Miguel Mateo La Salle, Juan Antonio Ricci, Simo Raittila, Stephen Laudig.
Note: This print is from an old version; it had a lot less content than the current one which is beyond being printable and hangable on a wall.
