11. Knowledge Aims / B. Certain Knowledge / 2. Common Sense Certainty
I can prove a hand exists, by holding one up, pointing to it, and saying 'here is one hand' [Moore,GE]
     Full Idea: I can prove now that two human hands exist. How? By holding up my two hands, and saying, as I make a certain gesture with the right hand, 'Here is one hand', and adding, as I gesture with the left, 'and here is another'.
     From: G.E. Moore (Proof of an External World [1939], p.1)
     A reaction: The words need to be spoken, presumably, so that what he is doing fits into the linguistic conventions of what will normally be accepted as a proof. In fact, just holding the hand up seems enough. The proof begs the question of virtual reality.
27. Natural Reality / A. Classical Physics / 1. Mechanics / d. Gravity
Gravity isn't a force, because it produces effects without diminishing [Mayer]
     Full Idea: If gravity be called a force, a cause is supposed which produces effects without itself diminishing, and incorrect conceptions of the causal connexions of things are thereby fostered.
     From: J.R. Mayer (Remarks on the forces of inorganic Nature [1842], p.199), quoted by Brian Ellis - Scientific Essentialism 8.03
     A reaction: This seems like a brilliant prelude to the proposal that gravity is actually the 'curvature' of space (whatever that is!).
29. Religion / B. Monotheistic Religion / 4. Christianity / d. Heresy
Philosophers are the forefathers of heretics [Tertullian]
     Full Idea: Philosophers are the forefathers of heretics.
     From: Tertullian (works [c.200]), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 20.2
29. Religion / D. Religious Issues / 1. Religious Commitment / e. Fideism
I believe because it is absurd [Tertullian]
     Full Idea: I believe because it is absurd ('Credo quia absurdum est').
     From: Tertullian (works [c.200]), quoted by Robert Fogelin - Walking the Tightrope of Reason n4.2
     A reaction: This seems to be a rather desperate remark, in response to what must have been rather good hostile arguments. No one would abandon the support of reason if it was easy to acquire. You can't deny its engaging romantic defiance, though.
