This paper aims at investing the possibilities for philosophical thinking through a speculative and critical examination of different ideas from various philosophers, such as Moore, Wittgenstein and Rorty. The aim is that philosophy can be a constructive part of the contemporary debate. In the first part, it is argued that philosophy is a speculative and universal business, and has had a great importance for society; examples of Plato, Aristotle, Augustine and different political philosophers as Marx, Mill, Rousseau and Hobbes are given. In the second part, society and science are investigated in relation to philosophy, and it is concluded that there is a fundamental difference between method and principles, in that methods always change while principles always are the same and this, it is said, is something fruitful for the possibilities and for the confidence in, philosophy. In the third part, the principles of philosophy are treated, and the contemporary world is treated in a historical perspective. The future of philosophy is discussed, and its strenght is said to lie in its own principles. It is argued that clearsightedness and precision can be the solution to philosophocal obscurity, but that there also thereby will be a risk of losing the genuine character and strenght of philosophy. The conclusion of the paper is that the possibilities of philosophy not are achieved by some new philosophical principles, but in a clearsighted use of the existing.
