Timeline of Western philosophers
|
A wide-ranging list of philosophers from the Western traditions of philosophy. Included are not only philosophers (Socrates, Plato), but also those who have had a marked importance upon the philosophy of the day (Copernicus, Einstein, Planck).
The list stops at the year 1950, where it is presumed that philosophers fall into the broader Global category.
The most popular or noteworthy philosophers can be found in bold, and slightly less influential philosophers are in italics.
Philosophers are organized roughly by the publication of their first, most influential works, or their "breakout" moments.
