Philosophy as practice does not mean its restriction to utility or applicability, that is, to what serves morality or produces serenity of soul.

The history of philosophy is not, like the history of the sciences, to be studied with the intellect alone. That which is receptive in us and that which impinges upon us from history is the reality of man's being, unfolding itself in thought.

At the present moment, the security of coherent philosophy, which existed from Parmenides to Hegel, is lost.

Philosophy is tested and characterised by the way in which it appropriates its history.

A common misconception about how things such as space shuttles come to be is that engineers simply apply the theories and equations of science. But this cannot be done until the new thing-to-be is conceived in the engineer's mind's eye. Rather than following from science, engineered things lead it.
