The expression 'free thought' is often used as if it meant merely opposition to the prevailing orthodoxy. But this is only a symptom of free thought, frequent, but invariable. 'Free thought' means thinking freely — as freely, at least, as is possible for a human being. The person who is free in any respect is free from something; what is the free thinker free from? To be worthy of the name, he must be free of two things: the force of tradition, and the tyrant of his own passions. No one is completely free from either, but in the measure of a man's emancipation he deserves to be called a free thinker.

Monado, although it may not be true of all cephalopods, some octopoda lose dangerous amounts of weight while protecting their young -- if that's her offspring, she's likely to take care of it.

Actually, in general, cephalopds taking care of (or even just laying) their eggs lose ALL of their body mass. Entirely dangerous.
Octopus moms don't bother eating, or healing up cuts and abrasions, or preventing bits of themselves from rotting away, while protecting/cleaning/aerating eggs. Her egg-babies tend to do better (== survive in larger proportions) if she manages to stay alive until they hatch.
Squids and cuttles tend to have to fend for themselves, even as naive developing eggs.
