Descartes, for me, is a great thinker. His meditation tries to penetrate the essence of reality with mind as the central of investigation. Even his method of idea, which almost the same as Plato’s idea through mimesis, has revealed that such archetype must be exist. And therefore, external beings, other than mind is also proved has to be existed.
Spinoza, trough his demonstration, refer to axiom and definition, also proved that God necessarily exist. And by substance, which in itself and conceived through itself and whose conception doesn’t need the conception of another thing from which it must be formed, he prove that Substance is indivisible, it is one and the cause of itself, that none should involve with which. Thus other cannot negate its existence.
Heidegger, through his ‘destruction’ method, destruct Cartesian and Spinoza’s and other modern philosophy method by questioning Being. If Descartes say ‘cogito ergo sum’, than Heidegger answer it by the question of Being itself. The question of Being has been forgotten for a long time, which is now once again has been questioned again.
Here, I see Heidegger is a bridge and transition to Derrida’s deconstruction.
Finally, Derrida through deconstruction method questioning the authority of logos. Which is the truth itself is inter-textual. The arche is shifted dynamically to always unknown and mystery of telos. The differance, which is the ‘ghost’, is always exist, and perhaps, it is the only one that exist, which destroy logosentrisism and metaphysics.
These four philosophers are my favorites. Nevertheless, I am now a little bit on Derrida side. So, I expect a critiques from you people to prove that Descartes or Spinoza could have argument to defeat Derrida’s elucidation in Deconstruction. In other words, I expect comments from ‘pro Descartes and Spinoza etc’, since I am myself a ‘pro Derrida , thx…
