1. Philosophy / D. Nature of Philosophy / 5. Aims of Philosophy / a. Philosophy as worldly
Philosophy aims to know the truth about the way things are [Aquinas]
     Full Idea: The study of philosophy has as its purpose to know not what people have thought, but rather the truth about the way things are.
     From: Thomas Aquinas (Sententia on 'De Caelo' [1268], I.22.228), quoted by Kretzmann/Stump - Aquinas, Thomas 05
     A reaction: I agree with this deeply unfashionable opinion. Of course, modern investigations must be more sensitive to biases built into language, culture and conceptual schemes. But I am one of those sad old folks who still think truths can be stated.
14. Science / D. Explanation / 2. Types of Explanation / k. Explanations by essence
Bohr explained the periodic table and chemical properties of elements, using the quantum atom [Kumar]
     Full Idea: Bohr used the quantum atom to explain the periodic table and the chemical properties of the elements. ...It was his new theory about the arrangement of electrons inside atoms that explained the placing and grouping of elements in the periodic table.
     From: Manjit Kumar (Quantum: Einstein and Bohr [2008], Ch 04)
     A reaction: (second sentence p.133) This is Exhibit A for the idea that essences are explanatory, and are discovered by scientists. The moot point would be whether it is appropriate to describe electron shells as part of the 'essence' of an atom.
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!).
