"..if we think of truth as something of granite-like solidity and of personality as something of rainbow-like intangibility and reflect that the aim of [human writing] is to weld these two into one seamless whole, we shall admit that the problem is a stiff one and that we need not wonder if [human writers], for the most part failed to solve it." - Virginia Woolf

[human writing, human writers] = [biography, biographers] in the original quote. My edit is because I infer that her statements key point is that of the biological subjectivity inherent to all human prose.
