Der Philosoph ist nicht Buerger einer Denkgemeinde. Das ist, was ihn zum Philosophen macht
(Ludwig Wittgenstein)
The secret to life is to have a task, something you devote your entire life to, something you bring everything to
, every minute of the day for your whole life. And the most important thing is - it must be something you cannot
possibly do
(Henry Moore)
Darahku merah tak sudi dijajah!
Ik en jij zijn samen wij (Felix Landsman)
Ik had nooit opgekeken tegen hoog, ook nooit neergekeken op laag (Johan Cruijff)
Ik kom uit Friesland. Ik loop niet voor andere meesters (Chris Zaal)
Door veel te begrijpen, heb ik niets af kunnen maken (the last words of Hugo de Groot)
Als componist schrijf je iets, je ziet wat je fout hebt gedaan en dat probeer je beter te doen. Dat proces gaat door tot je zeventigste, tachtigste
(Louis Andriessen)
Succes is niet een kwestie van een grote stap, maar van heel veel kleine stapjes. Je moet niet denken: ik wil vijftig winkels neerzetten. Je moet eerst die ene winkel goed doen. Je moet die ene bh goed kunnen maken (Marlies Dekkers)
I do not like this top ten business.
It is the bottom ten that I like. You have got to go for
the little things, the stones that make up the wall.
Science is a tremendous collaboration of people from
all over the world adding little bricks to a massive wall.
The individual bricks are what make it work,
and not the milestones (Donald Knuth)
Support of basic research in the universities and research institutes must
leave the internal control of policy, personnel, and the method and scope of
the research to the institutions themselves. This is of the utmost importance. (Vannevar Bush)
Dann giesst die Wissenschaft oft ihren wohltaetigen Segen auf das Leben aus, wenn sie dasselbe gewissermassen zu vergessen scheint (Wilhelm von Humboldt)
There is only one race: the human race (heard from black perfomer at Venice Beach)
The vulgarity of the present disgusted him. Kafu could only love in retrospect, and celebrate what has disappeared
(Ian Buruma, A Tokyo Romance, p. 55, about the Japanese writer Nagai Kafu)
If everything is under control, you're not going fast enough (Mario Andretti)
