The fish should be read from left to right, as if superimposed to a (horizontal)
time axis. The fish’s backbone represents what could be considered the ‘hegemonic’
current in the philosophy of science: its first stages as a professionalised
discipline—i.e. logical positivism, proposed by the Vienna Circle–, ranging from
the 1920s until World War II; the ‘received view’ in the 1940s–1960s, mainly
developed by English-speaking scholars; and—in the last decades—neo-positivistic
perspectives following the analytic tradition.
