The empirical successes of [the three-factor model] suggest that it is an equilibrium pricing model, a three-factor version of Merton's (1973) intertemporal CAPM (ICAPM) or Ross's (1976) arbitrage pricing theory (APT). In this view, SMB and HML mimic combinations of two underlying risk factors or state variables of special hedging concern to investors.

Einstein's relativity work is a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king... its exponents are brilliant men but they are metaphysicists rather than scientists.
Nikola Tesla
Just let matters slide. How much better to accept each sweet drop of the honey that was Time, than to stoop to the vulgarity latent in every decision. However grave the matter at hand might be, if one neglected it for long enough, the act of neglect itself would begin to affect the situation, and someone else would emerge as an ally. Such was Count Ayakura's version of political theory.
Yukio Mishima
Men who have sacrifice their well-being, and even their lives, for the cause of truth or the public good, are, from an empirical point of view - which scorn ("fait fi", Fr.) virtue and altruism - regarded as insane or fools; but, from a moral standpoint, they are heros who do honour ("qui honorent", Fr.) humanity.

In brief, nationalism is a theory of political legitimacy, which requires the ethnic boundaries should not be cut across political ones, and, in particular, that ethnic boundaries within a given state a contingency already formally excluded by the principle in its general formulation should not separate the power holders from the rest.
Ernest Gellner
I believe that economic theory has arrived at a point in its development where the appeal to quantitative empirical data has become more necessary than ever. At the same time its analyses have reached a degree of complexity that require the application of a more refined scientific method than that employed by the classical economists.
