Some questions for consideration:
If a philosopher remains in her/his bed, even for hours, attracted by the sublime desire to gain knowledge, driven by the passionate love of the truth, considering issues she/he finds the most interesting, would it be then reasonable to admit that she/he is working, or perhaps it`s nothing more than just laziness?
If a thinker clearly prefers a contemplative life, could an original and important philosophical theory be born this way? Or maybe an active life, gathering of various kinds of experience is essential for such an act of creativity?
