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:
“My philosophy is such that I am not going to vote against the oppressed. I have been oppressed, and so I am always going to have a vote for the oppressed, regardless of whether that oppressed is black or white or yellow or the people of the Middle East, or what. I have that feeling.”
—Septima Clark (1898–1987)
“When Philosophy with its abstractions paints grey in grey, the freshness and life of youth has gone, the reconciliation is not a reconciliation in the actual, but in the ideal world.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“The philosopher believes that the value of his philosophy lies in its totality, in its structure: posterity discovers it in the stones with which he built and with which other structures are subsequently built that are frequently better—and so, in the fact that that structure can be demolished and yet still possess value as material.”
—Friedrich Nietzsche (1844–1900)
