William Osler

There are, in truth, no specialties in medicine, since to know fully many of the most important diseases a man must be familiar with their manifestations in many organs.

In seeking absolute truth we aim at the unattainable and must be content with broken portions.

No human being is constituted to know the truth, the whole truth, and nothing but the truth and even the best of men must be content with fragments, with partial glimpses, never the full fruition.
