7 ideas

7. Existence / D. Theories of Reality / 2. Realism
12741 If experience is just a dream, it is still real enough if critical reason is never deceived [Leibniz]
     Full Idea: Even if this whole life were said to be only a dream, and the visible world only a phantasm, I should call this dream or phantasm real enough if we were never deceived by it when we make good use of reason.
     From: Gottfried Leibniz (De modo distinguendi phaenomena [1685], A6.4.1502), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 7
     A reaction: I find this response more satisfactory than his response in Idea 12740. As a supporter of the coherence account of justification, I take the closest we get to knowledge to be when our full critical faculties and experience are brought to bear, and shared.
12740 The strongest criterion that phenomena show reality is success in prediction [Leibniz]
     Full Idea: The most powerful criterion of the reality of phenomena, sufficient even by itself, is success in predicting future phenomena from past and present ones.
     From: Gottfried Leibniz (De modo distinguendi phaenomena [1685], A6.4.1502), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 7
     A reaction: I would say that this is clutching at straws, as there is no reason at all to deny that dreams could be thoroughly coherent and predictable in their events. We must just live with these doubts, not try to defeat them.
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / e. Primary/secondary critique
12721 Light, heat and colour are apparent qualities, and so are motion, figure and extension [Leibniz]
     Full Idea: Concerning bodies I can demonstrate that not merely light, heat, color, and similar qualities are apparent but also motion, figure, and extension.
     From: Gottfried Leibniz (De modo distinguendi phaenomena [1685], A6.4.1504), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 4
     A reaction: Leibniz is not consistent on this. Here he is flirting with idealism, but he often backs away from that. In Discourse §12 he makes secondary qualities certainly subjective, and primary qualities possibly so. He admits the primaries contain eternal truths.
21. Aesthetics / C. Artistic Issues / 7. Art and Morality
468 Musical performance can reveal a range of virtues [Damon of Ath.]
     Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice.
     From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where?
25. Social Practice / F. Life Issues / 3. Abortion
4054 I may exist before I become a person, just as I exist before I become an adult [Lockwood]
     Full Idea: It makes perfectly good sense to say that I existed before I became a person, just as I existed before I became an adult, or a philosopher.
     From: Michael Lockwood (When Does a Life Begin? [1985], p.13)
     A reaction: The word 'I' needs thought here. I was once a non-adult, but was I ever a non-person? 'Person' is not a clear concept, despite what many philosophers since Locke may think.
4056 If the soul is held to leave the body at brain-death, it should arrive at the time of brain-creation [Lockwood]
     Full Idea: Any Christian who feels that body and soul go their separate ways at brain death ought in consistency to hold that they come together only at the point when whatever is destroyed at brain death first came into being.
     From: Michael Lockwood (When Does a Life Begin? [1985], p.24)
     A reaction: Hence Christians probably focus less on brain-death than do doctors and the rest of us.
4055 It isn't obviously wicked to destroy a potential human being (e.g. an ununited egg and sperm) [Lockwood]
     Full Idea: A week-old embryo without a brain may be a potential human being, but so are a sperm and an ovum that are about to meet in a dish, and it wouldn't be wicked to keep those apart.
     From: Michael Lockwood (When Does a Life Begin? [1985], p.19)
     A reaction: Sounds fine, but it may be a slippery slope. Is it acceptable to deny a place at music school to a potentially great musician?
