10 ideas
19441 | All philosophies presuppose their historical moment, and arise from it [Feuerbach] |
Full Idea: Every philosophy originates as a manifestation of its time; its origin presupposes its historical time. | |
From: Ludwig Feuerbach (Towards a Critique of Hegel's Philosophy [1839], p.59) | |
A reaction: There seems to be widespread agreement among continental philosophers about this idea, whereas analytic philosophers largely ignore, and treat Plato as if he were a current professor in Chicago. |
19442 | I don't study Plato for his own sake; the primary aim is always understanding [Feuerbach] |
Full Idea: Plato in writing is only a means for me; that which is primary and a priori, that which is the ground to which all is ultimately referred, is understanding. | |
From: Ludwig Feuerbach (Towards a Critique of Hegel's Philosophy [1839], p.63) | |
A reaction: It always seems to that the main aim of philosophy is understanding - which is why its central activity is explanation. |
19445 | A dialectician has to be his own opponent [Feuerbach] |
Full Idea: A thinker is a dialectician only insofar as he is his own opponent. | |
From: Ludwig Feuerbach (Towards a Critique of Hegel's Philosophy [1839], p.72) | |
A reaction: Quite an inspirational slogan for beginners in philosophy. How many non-philosophers are willing to be their own opponent. In law courts and the House of Commons we assign the roles to separate persons. Hence rhetoric replaces reason? |
19444 | Each proposition has an antithesis, and truth exists as its refutation [Feuerbach] |
Full Idea: Every intellectual determination has its antithesis, its contradiction. Truth exists not in unity with, but in refutation of its opposite. | |
From: Ludwig Feuerbach (Towards a Critique of Hegel's Philosophy [1839], p.72) | |
A reaction: This appears to be a rejection of the 'synthesis' in Hegel, in favour of what strikes me as a rather more sensible interpretation of the modern dialectic. Being exists in contrast to nothingness, and truth exists in contrast to its negation? |
19443 | Truth forges an impersonal unity between people [Feuerbach] |
Full Idea: The urge to communicate is a fundamental urge - the urge for truth. ...That which is true belongs neither to me nor exclusively to you, but is common to all. The thought in which 'I' and 'You' are united is a true thought. | |
From: Ludwig Feuerbach (Towards a Critique of Hegel's Philosophy [1839], p.65) | |
A reaction: Sceptics may doubt that there are such truths, but this is certainly how we experience agreement - that there is some truth shared between us which is no longer the possession of either of us. Nice idea. |
10594 | Henkin semantics is more plausible for plural logic than for second-order logic [Maddy] |
Full Idea: Henkin-style semantics seem to me more plausible for plural logic than for second-order logic. | |
From: Penelope Maddy (Second Philosophy [2007], III.8 n1) | |
A reaction: Henkin-style semantics are presented by Shapiro as the standard semantics for second-order logic. |
19446 | To our consciousness it is language which looks unreal [Feuerbach] |
Full Idea: To sensuous consciousness it is precisely language that is unreal, nothing. | |
From: Ludwig Feuerbach (Towards a Critique of Hegel's Philosophy [1839], p.77) | |
A reaction: Offered as a corrective to the view that our ontological commitments entirely concern what we are willing to say. |
19447 | The Absolute is the 'and' which unites 'spirit and nature' [Feuerbach] |
Full Idea: The Absolute is spirit and nature. ...But what then is the Absolute? Nothing other than this 'and', that is, the unity of spirit and nature. | |
From: Ludwig Feuerbach (Towards a Critique of Hegel's Philosophy [1839], p.82) | |
A reaction: This is Feuerbach's spin on Hegel. He has been outlining idealist philosophy and the philosophy of nature in Schelling. Is this Spinoza's one substance? |
7458 | The reliability of witnesses depends on whether they benefit from their observations [Laplace, by Hacking] |
Full Idea: The credibility of a witness is in part a function of the story being reported. When the story claims to have infinite value, the temptation to lie for personal benefit is asymptotically infinite. | |
From: report of Pierre Simon de Laplace (Philosophical Essay on Probability [1820], Ch.XI) by Ian Hacking - The Emergence of Probability Ch.8 | |
A reaction: Laplace seems to especially have reports of miracles in mind. This observation certainly dashes any dreams one might have of producing a statistical measure of the reliability of testimony. |
3441 | If a supreme intellect knew all atoms and movements, it could know all of the past and the future [Laplace] |
Full Idea: An intelligence knowing at an instant the whole universe could know the movement of the largest bodies and atoms in one formula, provided his intellect were powerful enough to subject all data to analysis. Past and future would be present to his eyes. | |
From: Pierre Simon de Laplace (Philosophical Essay on Probability [1820]), quoted by Mark Thornton - Do we have free will? p.70 |
