Philosophy
In 1783, Kant wrote: "That everywhere space (which is not itself the boundary of another space) has three dimensions and that space in general cannot have more dimensions is based on the proposition that not more than three lines can intersect at right angles in one point. This proposition cannot at all be shown from concepts, but rests immediately on intuition and indeed on pure intuition a priori because it is apodictically (demonstrably) certain."

Famous quotes containing the word philosophy:
“The Emmet’s Inch and Eagle’s Mile
Make Lame Philosophy to smile.”
—William Blake (1757–1827)
“A cosmic philosophy is not constructed to fit a man; a cosmic philosophy is constructed to fit a cosmos. A man can no more possess a private religion than he can possess a private sun and moon.”
—Gilbert Keith Chesterton (1874–1936)
“How can you tell if you discipline effectively? Ask yourself if your disciplinary methods generally produce lasting results in a manner you find acceptable. Whether your philosophy is democratic or autocratic, whatever techniques you use—reasoning, a “star” chart, time-outs, or spanking—if it doesn’t work, it’s not effective.”
—Stanley Turecki (20th century)
